Caterpillar Rescue – Dagger in Distress!

Saturday, September 19, 2020. San Juan Island, WA – Caterpillar rescue!

Acronita impleta – Yellow-haired Dagger Moth caterpillar. San Juan Island, WA 09.19.2020


I found one of these several years ago (September 20, 2017 to be exact), so I recognized it immediately when I saw it squirming in the spider webbing along the house this morning. My husband said I should just leave it alone. “Nature is ugly sometimes and you can’t interfere.” Well, when it was still there four hours later, suspended mid air, and still squirming, my tendency to SAVE things kicked in. The spider living above that web was actually dead. I’m not feeling very guilty about stealing food from a dead spider.

I got a cup and gently pulled at the web and began the process of freeing this caterpillar. It took finding my reading glasses and getting some fine-pointed tools to gently ply away the sticky bonds and clean the strands off the caterpillar hairs.

I think it looks pretty good! I even picked it some dinner and we’ll see if I can keep it healthy through pupation and adulthood.

Spider Sleuthing in the San Juans – Day 11 – Arachnid Advocates Needed

I had to take the weekend off! Fatigue is setting in from the smoke and the yellow haze cast over the island isn’t helping. I’m weary of viewing responses from folks about how they want to “kill” any poor hapless spider that makes its way into their home. Arachnophobia is tough, but thousands of innocent creatures could escape a horrible death (stomping, squishing, flushing) as a result of human hysteria if only….if ONLY…that human might take a moment to educate themselves about the poor soul they just MURDERED. If you are guilty of this and you’re feeling badly, GOOD! It means there is hope for you to change your ways. Become an arachnid A-D-V-O-C-A-T-E!

A friend of mine shared the article linked below on Facebook today. It’s timely in that it speaks to the over sensationalized media reports that cast a negative light on spiders…and other insects. We need to change how we think of them! Check it out.

For today, please don’t relocate your little (or big) house spider outdoors! Leave it in the corner to do its thing. It’s going to wander a bit, but it isn’t going to bite you or harm your pets. Be curious about it. If you name it, it can become part of your family! If you want an ID for that spider, send me a message or post a photo on my Facebook Page (Bugs of the San Juan Islands).

September Spider Sleuthing in the San Juans – Day 8 Araneus diadematus, the Cross Orb weaver

Yesterday my husband was outside working on our deck (without much help from me). The weekend projects can be overwhelming, especially when I’m so easily distracted every time I find a BUG. This one was perfect for my post today!

Female Cross Orb Weaver, Araneus diadematus 09.07.2020

First off, it’s a SHE spider! This fall beauty is a female Cross Orb Weaver, Araneus diadematus. She was hanging out on the side of the house, just under the eave. I had to carefully climb a ladder to get a photo, but it was completely worth the risk.

Female Cross Orb Weaver, Araneus diadematus 09.07.2020

Orb Weavers are in the family Araneidae. These are some of the most beautiful and commonly seen spiders in our area. They weave the classic and typically vertical, orb-shaped web that we often see in our gardens.

While Araneus diadematus is not a native species and was introduced from Western and Northern Europe, it has become naturalized here and ranges across North America now. Bugguide.net gives the North American (including Canada) range for A. diadematus as the following localities – “diadematus – BC, WA, OR, MI, OH, PA, ON, NY, QC, RI, MA, NS, NL.”

Male and female specimens have different morphology (size, shape). Female body length can be from 6-20mm and they are fuller and more rounded. Male body length varies from 6-13mm and they are more narrowed in body shape.

Male A. diadematus

Typically, even though they are around in spring, we don’t notice them until later in the fall (like now). Females will be waiting on their web for a wandering male to find them. Males are not usually seen on webs since they are often on the move to find “Miss Right.”

The female A. diadematus will lay her last clutch of eggs in fall before dying, usually timed with our first frost. The eggs will overwinter. The eggs will hatch in springtime when temperatures warm, releasing hundreds of baby spiderlings!

June 13, 2013 – San Juan Island “Orb-Weaver Spiderlings”

I found this interesting poem online about Orb Weavers that I’ll leave you with today. Thanks for stopping by!

Araneus diadematus

Our cradle empty, we shall climb

To a high place, to catch the wind

And fly, strewing gossamer as we go,

Singly, flowing without will, to land

Wherever.

We shall know, by the compass

Blotched in white upon our backs,

Where to spin the spokes, and how

To spire the wheel; with one leg, feel

The trembling.

Approach too fast, and we shall quake,

And blur the whorl with shaking

From the underside, the compass

Pointing down, our legs the eight points

Taking.

At night we eat the orb, conserve

The silk, to spin again by morning,

Indelicately, cramming all

Into open mouths, every spoke

Consuming.

We spin the globes of nurture

After mating, span them so,

With loving claws, adore the

Minor worlds we make, compass

Turning.

Entwined in silk, their spinnerets

Are forming, massed bundles

Of eyes, and legs, and fangs

Entangling. Each of us

Expiring.

The common “Garden Spider” has a characteristic “cross” on its back, and is the archetypal orb-weaver. Immatures, already orphans by the time they emerge, go out to seek their fortunes by abseiling more or less at random on air-currents, attached to an anchor point by nothing but a thread of gossamer.

Spider Sleuthing in The San Juans – Day 7 Debunking Spider myths

Today, I’m going to introduce you to Rod Crawford in my post. Rod is the curator and spider expert (GENIUS) at the Burke Museum in Seattle. He is the go-to guy for anything you would possibly want to know about spiders.

One thing I really like about Rod are his efforts to debunk some of the most common myths about spiders. For instance, putting that spider you find in your house outdoors is good for the spider and where it belongs. Nope. Nope. Nope,….and one more big ole’ NOPE! Take a look here to read what Rod says about where some spiders live (including indoors), and why tossing them outdoors is not a good idea.

Spider Sleuthing in the San Juans – Day 5 Be Nice to Spiders!


When I was a little girl, my mom read me this book, “Be Nice to Spiders.” We read it together many, many times! It was probably one of my earliest introductions to the wonder of ecological systems and definitely played a role in the development of my love for animals and nature.

My mom didn’t have the opportunity for a college education and was a pretty young mom at 23. She did however, grow up in the mountains of North Carolina, loved nature, and she had a “story” for everything! It made learning about leaves, bugs, rocks, and animals of all kinds really fun.

I was extremely lucky to have a mom like that and to be exposed to so many science opportunities, even though I didn’t really see it as science at the time. As a parent myself, and someone with a background in education, I can’t express enough to other parents out there how important it is to connect your children with nature…in a kind way! Help them to see living things with wonder and respect for all life. Especially spiders!

Here’s a YouTube read aloud of Be Nice to Spiders. There were several, but I just liked this woman for some reason. I’m sure the San Juan Island library has a copy of the book too, and if not, there’s always Griffin Bay Books, Serendipity, Abebooks, and Amazon where you can find a copy for your bookshelf.

Sleuthing Spiders Day 4- Why is that spider in my bathtub?

hello!

There could be a few reasons you’re finding that spider in your sink or bathtub or shower! 

Reason #1 –  Lots of spiders are nocturnal, so while we’re sleeping they’re stealthily crossing the ceiling overhead.  Sometimes one may bungee down to check things out below.  If that happens to be over the tub, it’s possible the poor little (or BIG) spider just got stuck, unable to scale the walls of a slippery surface.  

 Same thing with the kitchen sink.  A spider scurries across the counter too fast, one of those 8 legs slips or maybe a knee buckles (yes, spiders have knees), and the next thing that spider is facing is our equivalent of falling down into a deep well. 

 He…or SHE, needs someone to throw in a lifeline to get back out.  


Reason #2 – Sometimes…yes, sometimes spiders end up in your tub or shower or sink because deep in the cracks or seals around the shower door or down in the drain, you have these teeny little spider snacks squirming around.  That’s right!  You might not see them, but even if your shower is squeaky clean, you probably have drain fly larvae living in your pipes. 

 Yikes!  I got into our shower one morning and there were these teeny little wiggly worms down at my feet.  When I poked around the rubber strip that prevents water from leaking out the shower door, there were MORE!  


To help you visualize this,  I’ll try and get creative.  I’m not a very good drawer, so I scribbled in the wriggling larvae to enhance this image I found online.   In my mind, I pictured the woman in the movie Psycho, screaming at the top of her lungs since the scientific name for drainflies is Pscho-di-dae! 

The adults aren’t scary looking at all though.  They’re called Moth Flies and they are sort of cute…and fuzzy-wuzzy!   The larvae, also called sewer flies, actually are beneficial and help purify water, so I am viewing them now as an important part of an ecosystem while trying to get over being creeped out by them around my feet.  


I also am much more welcoming to my house spiders now that I know they are working hard to save me from DRAIN FLIES!

Reason #3 – Did you know that spiders drink water?  Yes…sometimes spiders end up in the sink, bathtub, or shower because spiders get thirsty! I actually had a little spider I found in my home that was in a declining way and Rod Crawford (also known as the Spider Whisperer) at the Burke Museum messaged me about how to give it a drink. Here’s what he said, “For future reference, the way to give a spider a drink is to rest the mouth area (under the front of the “head”) directly in a drop of water.”   I must confess that now I’m so sensitive to spiders needing water that whenever I get one out of the bathtub, I’ve put a moistened cotton ball on the floor nearby so it won’t die of thirst!  

Please be my friend! (Salticus scenicus), a little jumper ❤️

Sleuthing Spiders in the San Juans – Day 3 – Classifying Spiders, the Very Beginner Basics!

Spider Sleuthing Day 3 – Classifying Spiders. The (VERY) Beginner Basics. Spider classification (for North America) consists basically of two different groups. These are the infraorders: Araneomorphae (the “true” spiders) and Mygalomorphae (the tarantulas and trapdoor spiders).

What are “true” spiders? Why those are the ones that aren’t Mygalomorphs! What??? I confess, I’m having to read up on this as I type this post. I DID, however, disclose that I am an entomologist and not an arachnologist in my DAY 2 post, and I can count to 6 (if you read my earlier post, you’ll get my joke), and that is high enough to tell you that these groups are partially differentiated by the number of book lungs a spider has.

Book lungs are the main respiratory organ in arachnids. Mygalomorphs have 4 book lungs and Araneomorphs have only 2. See, we got to SIX! 😁

The other difference between these two spider groups has to do with how they chew. Well, sort of. A more scientific description would be to say the directionality of movement of their chelicerae.

Yep. Let’s just make it easy today and say, Mygalomorph’s mouthparts move in a parallel direction (move your first two fingers towards each other like you’re making air quotes) and Araneomorph’s mouthparts are oriented in an opposing way (touch your forefinger to your thumb in a pincer-like way). For more about this, you’re welcome to delve into the deep world of spider systematics here – https://www.jstor.org/stable/2097274?seq=1#metadata_info_tab_contents

Sorting spiders involves numerous other factors including morphological differences such as eye arrangement, hairs, body shape, number of claws and even what type of web they make or whether they make a web at all!

As to webs, well that’s going to be a post of its own. There are ALL sorts of webs and knowing their names and being able to identify them will be a tool for figuring out what sort of spider you may have.

I have run out of time for my post today, but I will leave you with a few links to check out so you can learn more of the basic morphology that all spiders share: 8 legs, head or (cephalothorax region), abdomen…Oh, and the cutie on my finger is one of my house spider friends. She’s a jumping spider (Salticus scenicus) and her name is Skipper.

***Hint to remembering the Mygalomorphs – *The majority of species in the Mygalomorphae are tarantulas, in the family Theraphosidae (in French, a tarantula is called a ‘mygale’

The Three Banded Lady Beetle (Coccinella trifasciata subversa)

Coccinella trifasciata subversa on clover

I found my first Three Banded Lady Beetle (Coccinella trifasciata subversa) this morning in the patch of clover in front of my home. At least I believe it is the subspecies ‘subversa’ according to the information I found online and referencing the distribution map. While I did not find much information about this particular species pertaining to life in the Pacific Northwest, I did find that according to the Lost Ladybug Project, this species (Coccinella trifasciata) is considered a species of greatest conservation need in the state of New York.

So, because I’m interested in Lady Beetles and conservation, I submitted my photos today to the Lost Ladybug Project. They’re keeping records of sightings and I believe it’s important to collect and share data that help us understand more about the lives all of all the amazing critters we share the planet with.

If you see a Lady Beetle you are interested in knowing more about, take a look at the Lost Ladybug Project here – http://www.lostladybug.org/index.php

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.

Cicurina spp. February 19, 2020

This spider is in the genus Cicurina, also known as the Cave Meshweaver or Cave Spider. Pronounced “sik-uhr-EYE-nuh,” the Latin name translates to “tame” or “mild.”

From Buggide.net and according to Rod Crawford:

Cicurina of Western Washington: “C. pusilla is by far the commonest. C. simplex and C. “idahoana” (really an undescribed species related to idahoana, in my opinion) are moderately common. Cicurina tersa is less common than the previous three. The other Cicurina of western Washington are actually rare here, C. tacomaand C. intermedia.” ~Rod Crawford
