This fly was in my yard last week. San Juan Island, WA. 06.19.2021. It’s taken me about a week to get around to ID, but I believe this to be Eupeodes fumipennis (the Western Aphideater, a syrphid fly that happens to be a bee mimic.
In case you are wondering about that name. The Western Aphideater does actually eat aphids in the larval stage. To see what a syrphid fly larva looks like in action, check out my blog post with more video footage here –https://buggingyoufromsanjuanisland.com/…/honeysuckle…/ – also viewable in the photo below. While I have not been able to identify the species name of the syrphid fly larva in that post, you can definitely see where the Western Aphideater fly might get its name.
I photographed these tiny, delicate eggs this morning using my macro lens attachment and my iPhone camera. Yesterday evening (July 30, 2019), I picked a leaf from my plum tree because I saw something odd. Not these eggs because they were far too small to see without magnification. Instead, I saw fuzzy white particles that sure looked to me like pest insects had taken up residence. I’m sharing the eggs in this post first. I believe they’re lacewing eggs. Lacewings are beneficial in the garden and voracious predators of small, soft-bodied insects. Check back tomorrow for Part 2 where I’ll share the rest of my discovery with some video of what else I found on those leaves.
