A Beneficial Buzz!


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.
