The House Pseudoscorpion (Cheliferidae cancroides)

I got the coolest picture of a bug on Friday!

This little creature was photographed on February 28, 2020 by Trever Santora on San Juan Island, WA.

It’s a Pseudoscorpion! Found on the windowsill of his house and no larger than a tiny sesame seed, I believe it to be an immature House Pseudoscorpion (Cheliferidae cancroides). 

Keep an eye out for these. They’re quite harmless to humans and can’t sting or bite you. Pseudoscorpions are predacious and beneficial because they eat other organisms that are pests. Some live in birds’ nests and eat the mites that can build up and harm nestlings. 

Since they don’t have wings and can’t fly, pseudoscorpions move around by phoresy. That means they’ll hitch a ride on someone who can! Not just birds, but bees, wasps, and flies can also provide a free lift.

Long-horned Leaf Beetle (Plateumaris germari)

I really enjoy the days when I have an opportunity to go over insect images I’ve taken, but haven’t yet had the chance to identify. This small (approx 7-8mm), metallic beetle is a leaf beetle in the family Chrysomelidae. It’s a Long-horned Leaf Beetle (Plateumaris germari). They are associated with aquatic habitats and this specimen was found near a wetland habitat on San Juan Island, WA., May 12, 2015. Yes. I’m slow at getting around to sorting things, but was happy to share this one today.

Pardosa spp. Thin-legged Wolf Spider

Here’s another spider for you. I photographed this one yesterday, February 22, 2019, on the dirt road near my home on San Juan Island, WA. There were two of them, but in the past, I’ve seen up to twenty crawling around (and they move extremely fast) in this (usually sunny) spot. My ID attempt here is that it’s some type of wolf spider. Size is approximately 3-4mm. The photos were taken with a macro clip on lens for iPhone.

Forest Co-habitating Microfauna

Yesterday, my husband took me for a walk in the woods near our home and while I always enjoy the fresh air and the quiet beauty of the woods, I especially appreciate the opportunity to discover new bugs. I was really hoping to come across one beetle in particular, a ground beetle that I’ve only seen three times since September 2009, when I first moved to San Juan Island.

It’s called Matthews’ Angry Gnashing Beetle or Zacotus matthewsii. Zacotus means “very angry” in Greek, though I’m not sure why this beetle would ever act in an angry manner unless you were poking it with a stick. In that case, it’s likely it would attempt to defend itself by gnashing at you with its mandibles, and any bites you receive would be well deserved indeed!

The last sighting I had of a live Zacotus matthewsii was February 18, 2015 at 5:56 p.m. I’m hoping to walk along the same spot again this evening about the same time in hopes of sighting another.

These ground beetles are extremely unique. Their maroon-red metallic coloring is often ringed with a green shimmer along the margins of its body.

Sadly, the life history of these beetles is understudied. We do know they are only associated with old growth forest ecosystems and rarely seen. When old-growth forests are cut down, the beetles disappear and our opportunity to know them is lost.

While I didn’t find one of these beetles yesterday on our walk in the forest, I did come across some equally interesting residents, cohabitating in a rotten log near a stream. I might have missed them entirely, but for my curiosity leading me to lift off a section of the log. It was a bit like lifting the roof off a house, and being able to see all the rooms and inhabitants, only instead of being a multi-family unit, this was a multi-species, multi-family unit!

I’d packed my cellphone and my handy clip on macro lens, so I was able to take some video and photos to share with you. Here’s what I found!

The first amazing creature that was exposed in the log was a centipede. This is Scolopocryptops spinicaudus. I noticed nearby, there was a grouping of eggs, so after a bit of internet searching, I discovered the very neat fact that these (and other species) of centipedes stay with their eggs.

The mother will wrap herself around the cluster to better protect them, staying with her brood even weeks after they hatch, leaving them only after they are able to fend for themselves. I believe this mother centipede moved away from her eggs when I removed the section from the log in order to draw my attention away from them.

***Eggs were not disturbed and I replaced the log section after taking my photos.

Below is a photo I found when I was searching about centipedes and parental care. I find it amazing that even invertebrates show such care for their offspring!

The next resident in the log that caught my eye was the very tiny, whitish-translucent, globular creature that looked a lot like a bark or booklouse, but turned out to be a “baby” termite. These were larvae of the Pacific Dampwood Termite, Zootermopsis angusticollis. I wasn’t able to get a good view, but it looked as if these were being tended by an older family member.

Dampwood termites are widespread in Pacific Northwest forests. They rarely cause damage to structures, but play a very important ecological role, recycling nutrients from decaying trees. They are also food for Pileated Woodpeckers and other birds and animals.

Finally, the last residents I spied cohabitating in this section of rotting log were the very tiny Wrinkled Bark Beetles (Clinidium spp.) Clinidium spp. of bark beetles feed on slime molds (Myxomycetes), found in decaying or dead hardwoods and conifers. They are in the Family Rhysodidae and there are only two genera and eight species in North America. Only two of these eight species range in the West (from California to B.C. ) (White, 1983).

At about 5mm in length, these were hard to detect with the naked eye. I took the following photos with my macro lens, showing the striations along the elytra and the lateral grooves on the basal half of the pronoun.

The next photo shows two adults together, presumably hibernating together in a cavity in the rotting log (White, 1983) .

Corona-bug

Coronavirus

Someone in San Juan County is being tested by the CDC for possible infection with the novel coronavirus (COVID-19). The person’s ID and island of residence has not been released. If confirmed, this would be the first instance of the virus in San Juan County and the second case in WA state. https://www.sanjuanjournal.com/news/person-under-investigation-for-novel-coronavirus/

The Coronavirus is named after the crown-like spikes found on the surface of the virus. In Latin, “corona” means ‘crown.’ You can view microscopic images of the virus on NPR’s site here ~ https://www.npr.org/2020/02/13/805837103/images-what-new-coronavirus-looks-like-under-the-microscope

Information about the virus, symptoms, etc. can be found on the CDC website here ~ https://www.cdc.gov/coronavirus/about/index.html , with further information on the virus, published by the Coronavirus Study Group (CSG) of the International Committee on Taxonomy of Viruses found here – https://www.biorxiv.org/content/10.1101/2020.02.07.937862v1.full Researchers have also found that the coronavirus can live on fomites (surfaces) for 9 days https://eurekalert.org/pub_releases/2020-02/rb-hlc020720.php Pharmaceutical treatment of this virus is sketchy at best. Read about the difficulty of treating viruses and what research is happening here ~ https://www.livescience.com/possible-treatments-new-coronavirus.html

Lots of folks think living on an island is some sort of safe haven. I’ve spent a bit of time thinking about this and I just don’t believe that to be true. First off, if everyone got sick, we definitely do NOT have the capacity to care for people in hospitals. Probably we would quickly run out of supplies. It’s really doubtful that anyone would want to deliver things to the island if we had some type of epidemic. We could easily run out of food and fuel.

Image result for The Scream

If I’ve learned anything in the ten-plus years I’ve lived here, it’s that you should be prepared to care for yourself. Whether it’s an earthquake or other natural disaster, government breakdown (that could certainly happen given our current administration), or disease outbreak, a plan is essential! While I know we have some truly dedicated medical professionals on our island, they are limited. There’s also not any prescription drug that will cure you of coronavirus if you get it. This links to the limited treatment options that may be available or under development https://www.livescience.com/possible-treatments-new-coronavirus.html

So, my plan (if anyone in my household gets sick) is to have my self-treatment items in order. Here’s my list:

  1. Elderberry syrup. Elderberry contains Sambucol which has been clinically proven to reduce the severity and duration of viruses. For more information, see my extensive reference list below. I keep this brand for myself. Natures Answer Elderberry Syrup ~ https://www.amazon.com/gp/product/B0007CSCIS/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
  2. Vitamin C. Vitamin C helps oxygenate your blood and supports your immune system. I take about 6000 mg of American Health Ester C in divided doses daily. I like this brand because it’s easier on my stomach ~ https://www.amazon.com/gp/product/B000MMWJHI/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
  3. Quercetin. https://www.amazon.com/Thorne-Research-Quercetin-Antioxidant-Supplement/dp/B0797DQTVZ/ref=sr_1_1_sspa?keywords=Quercetin+Thorne&qid=1581704516&s=hpc&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFON1Y3M0VRWDk4VFImZW5jcnlwdGVkSWQ9QTAzMjYzNTkxWVpCM1NZNThNRlpMJmVuY3J5cHRlZEFkSWQ9QTAzMjc0MTcxT1FNODRVOVJKR04wJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ==
  4. Pedialyte, Gatorade, and Ginger Ale. For rehydration!
  5. Lemon Balm. Strong antiviral properties. Use a tincture or make a tea.
  6. Ginger. Also strong antiviral properties.
  7. Saltine Crackers
  8. White rice
  9. Licorice Tea
  10. Lysine
  11. Saline Spray
  12. Motrin/Tylenol
  13. Vick’s Vapor Rub

If you can think of anything I might have left off, please feel free to write and let me know! P.S. I’m not a doctor. These are my own HOME remedies. Use your own good judgement and wash your hands a lot!

Slime WHAT? I’m flux-moxed!

I knew the headline would be catchy! I was indeed flummoxed (or greatly bewildered) when I saw the foam blobs on our Douglas fir trees today after the rain subsided enough for me to walk around outside. We’ve had a DELUGE of rain in the Pacific Northwest this year. Rumor has it, the rain is record-setting!

Back to the giant spit-wad looking blobs of bubbles on those trees…. Here’s what I saw.

Pseudotsuga menziesii Douglas fir trunk with foam blob

I’m an entomologist, so when I saw this I thought, “it sure looks a lot like the foamy froth that spittle bugs make.” However, I quickly discounted this possibility (unless there was some sort of really LARGE undiscovered species hiding out on San Juan Island that is) because it’s way too early in the season for them.

What WOULD we do without Google? Seriously! I typed in a search. My first query was “what do Pacific tree frog eggs look like?” I was skeptical, but since I heard tree frogs around me in the woods and since it is REALLY wet outside, I thought maybe one or two of these frogs got confused and used the tree instead of one of the thousands of water puddles I was trying to avoid stepping in. Nope. Not tree frogs. My next query read like this…”weird, foam mass on Douglas fir tree trunk.” I got a few things, but quickly narrowed the possibility to the sites that had photos that looked like mine.

I discovered these oozing foamy spots are called SLIME FLUX, also known as a condition of the tree called WETWOOD. Sounds bad. Might be.

I’ve not had a chance to read through all of this material. It sure seems like there is a link between harmful bacteria, water, possibly insects, and the resulting foam. but will share it here for you to reference. https://www.fs.fed.us/pnw/pubs/pnw_gtr112.pdf

While scanning this document, the term that popped out at me was “slime-flux insects” on page 8. I’ll have to do some more reading to investigate this. If you beat me to it, please feel free to share your comments. Curious minds want to know!

***Update

I’ve been doing a bit more reading about slime flux and foamy trees this evening (check out this site http://www.wonderofeverydaynature.com/2016/03/26/155/) and found an alternative and possibly more probable cause. While the foam can be caused by bacterial infections, it also is known to form after periods of heavy rain when a chemical reaction of sorts occurs. The rain interacts with soap-like components found in the sap from pine trees (and probably this includes fir trees as well), creating foam similar to what I observed today. It can also form from air pollutants that land on the trees after dry periods and create foam when rain hits the tree bark.

Fi Fi Fo Foam! I learned the best way to tell the difference between friend or foe foam is to take a whiff. Bacterial infections produce a foul-smelling foam that bubbles out as tree tissue is broken down, forming alcohol and carbon dioxide gas. This foam will often attract insects like bees, flies, wasps, and ants.

The most-detailed explanation about what happens during this process I found on the Penn State Extension Website, and I’ve copied below from their site (found here ~ https://extension.psu.edu/bacterial-wetwood-or-slime-flux

“Bacteria, commonly found in soil and water, take up residence in young trees or gain entrance to older trees through wounds. The bacteria, including species of Clostridium, Bacillus, Enterobacter, Klebsiella, and Pseudomonas, grow within the tree using the sap as a nutrient source. As the sap is used, oxygen in the heartwood is depleted (creating anaerobic conditions), methane is produced, the pH of the sap is increased (pH 6 in healthy trees to pH 7 to 8 in wetwood), and a high pressure develops in the wood (60 psi in affected trees vs. 5-10 psi in wetwood-free trees). The resulting environment greatly inhibits the growth of fungi that can cause interior rots. The liquid kills grass and other herbaceous plants that it contacts at the base of the tree. The wood of affected trees has greatly reduced value as lumber because of the unsightly discoloration. Affected wood dries much more slowly than wood taken from wetwood-free trees.”

Another good page to check out if you want to read more about slime flux or Wetwood is found at forestpathology.org ~ https://forestpathology.org/bacterial-viral-diseases/wetwood/

Blister Beetles

San Juan Island, WA 11/2/2019

I posted back in April about an encounter with Blister Beetles not far from my house. You can read about that here ~ (https://cynthiabrast.wordpress.com/2019/04/16/a-blistery-spring-day/ ). Over the weekend of November 2-3, I came across quite a few more of these in the exact same spot as in April. This time I didn’t see any live beetles, but there were at least 25-30 dead in the road.

Meloe strigulosus
San Juan Island, WA
11/2/2019

Ever the opportunist, I scraped up as many that weren’t quite so smushed into a container and brought them home. Out of the 5 I collected, 2 were male, 2 were female, and one missed antennae altogether. Given the number of beetles in the road in this one spot, I believe this was a mating aggregation.

Meloe strigulosus (male)

So, I’ve been reading about them and communicating with a two experts on blister beetles. If you don’t know what these are, they are significant because of a defensive chemical in them called Cantharidin. Cantharidin is quite toxic and it’s a blistering agent. This is where they got the name Blister Beetles in the first place.

antennal segmentation of male Meloe strigulosus
San Juan Island, WA
11/2/2019

Since my first sighting of these beetles back in April, I’ve learned quite a bit about them. The ones here (Meloe strigulosus) are black, flightless, tanker-like beetles, carrying around a cargo of toxic brew. They are sometimes a hazard to livestock (actually almost all mammals) that might eat them because the Cantharidin is toxic. Horses, goats, cows, and sheep that eat alfalfa hay can get really sick with colic if there are even parts of dead beetles in the hay.

While we don’t really know exactly how Cantharidin is produced in the beetle, we do know these two things: 1) it’s produced in the male and transferred to the female during mating. 2) the female transfers Cantharidin as a protective coating for her eggs during oviposition. It’s believed that the first instar larvae (called triungulin) are equipped with a supply of Cantharidin as well.

After hatching, the triungulin crawl up onto flowers to hang out and wait to attach to the hairs of a visiting bee, riding back to its nesting site. The later developmental stages of larvae are protected underground or in holes in wood where native bees are developing. They consume the developing bee eggs, larvae and nest provisions (pollen and nectar).

Is there anything good about blister beetles? Well, strangely, the populations of some species of blister beetles are timed to coincide with grasshopper abundance. Adult blister beetles feed on grasshopper eggs. That’s good, right?

What else? Humans have used Cantharidin for years to remove warts and to remove tattoos as well. For ages, it has been used as a sexual stimulant. Even birds called Great Bustards have picked up on this! Read more here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6521026/

Blister beetles seem to be beneficial to some other species of beetles too. There is one beetle that actually has been found to chew on the blister beetle as a means of obtaining Cantharidin for its own protection. Other animals like toads, frogs, and armadillos are known to eat these beetles or use them in some way to confer protection. There is even a nuthatch that uses the beetle to “sweep” the wood where it wants to build a nest to protect it from parasites.

Back to my weekend sighting and collection of a few of these specimens. I had two that were intact enough to pin for my collection. I wore nitrile gloves to make sure I didn’t come into contact with any blistering agent. It’s a good thing I did. Some fluid made contact with one of the fingers of my gloved hand and actually started eating through it. That’s pretty caustic!

If you’re interested in more information about them, I’m happy to email some of my collected literature. There are also links you can check out in my previous post from April.

Thanks for reading!

Honeysuckle aphid (Rhopalomyzus lonicerae) on Reed Canary Grass being eaten by a Syrphid fly larva

Honeysuckle aphid (Rhopalomyzus lonicerae) on Reed Canary Grass
Honeysuckle aphids on Reed Canary Grass

I photographed and filmed these tiny white “lambs” over the weekend (Sept. 21, 2019). There is a patch of Reed canary grass growing in a wetland area near my house and I wanted to see what sort of insects I might find associated with this particular plant.

These “lambs” are actually Honeysuckle aphids (Rhopalomyzus lonicerae). The species epithet, lonicerae refers to honeysuckle. These particular aphids live on honeysuckle in the winter and in grasses (as in the Reed Canary grass) in summer (4,5). The creamy white form (pictured above) are wingless, sub-adults, the apterae (without-wings) ~ Aphid glossary here: https://influentialpoints.com/aphid/Aphid-glossary.htm . There were quite a few of them and they were huddled together somewhat herd-like (see video below) on the grass stems. I did spot an adult or two (photo below), dispersed in other patches of grass, but absent from the groups of young.

The most amazing part to me was the “wolf” disguised in my herd of aphid lambs. This big bad wolf was actually a syrphid fly larva devouring one little lamb after another. It surprised me that they all waited, rather obediently, without resistance, as one after another was sucked dry by the fly-wolf. Note the dried out skins remaining on the leaf when you view the videos of the little lambs I found in the grass below. 🐑

Reed canary grass (Phalaris arundinacea) is in the plant family Poacea. Historically, reed canary grass has been considered good fodder for livestock, especially in areas too wet to grow traditional hay crops (3). In Washington State, it is now considered a non-native, noxious weed by the Washington State Noxious Weed Control Board (1). However in further review of literature about this plant, I came across one publication contradicting this view. This one cites published research that, in the Pacific Northwest there is evidence that some varieties of this widespread “circumboreal” grass are native to Western North America (2) .

Native? Noxious? Invasive? If you want to read more about Reed Canary grass, please do take a minute to check out the referenced links below.

Got Aphids? Honey, Dew I!

"BUGGING" YOU FROM San Juan Island's avatarBugging You From San Juan Island

Black Aphids

These tiny pear-shaped insects can be a serious garden pest. Aphids use their long slender mouthparts like a syringe, piercing the tender parts of plants and sucking out the juices….but this isn’t the only way they damage your plants. Feeding aphids also excrete a sticky waste byproduct called honeydew – honeydew helps the sooty mold fungus grow and sooty mold fungus blocks the plant from getting enough sunlight. No sunlight…no photosynthesis! The leaves of your plant can drop off and die. What other ways do aphids damage your plants? When they feed, they also can inject the plant with pathogenic viruses. These aphid-transmitted viruses can cause plants to yellow, leaves to curl and the plant’s growth will often be stunted.

Compounding the problem is the rate at which these “little devils” multiply. Why call them “devils?” I like to refer to them that way because it helps me…
