About this episode
Flower flies, a.k.a. hover flies, are common garden visitors, but they are often overlooked. The reason they are so often overlooked is because they are extraordinary mimics, usually of bees or wasps. Their mimicry is so good, that flower flies are often mistakenly identified as bees in social media posts, magazine articles, newsletters, and sometimes even books. In this week's episode of the Backyard Ecology podcast, we are talking with Dr. Jeff Skevington and Michelle Locke. Jeff and Michelle are co-authors authors of the book Field Guide to the Flower Flies of Northeastern North America. Their book covers the flower flies found from the Mississippi River across to the east coast and from Kentucky north all the way into Greenland. However, the book includes full distribution range maps for each species, so it will still be relevant for many areas outside of its primary focal range, especially in the eastern half of the continent. Our conversation covered many different topics including the life history of flower flies, where and when to look for them, and some fascinating behaviors like hilltopping and migrating. We also talked about how to identify flower flies, starting with how to know you are looking at a flower fly and not a bee or wasp. Michelle and Jeff are both extremely knowledgeable. I learned a lot from our conversation. Even though flower flies are important pollinators, there is still much that we don't know about them. It's really hard to manage for a species, or protect it if necessary, without basic information like knowing its full life history or population numbers and distribution. Yet, basic information like that is unknown for many species of flower flies. Multiple times throughout our conversation, Jeff and Michelle mentioned simple ways we could help fill in those knowledge gaps.
