Your letter to the bugman: Dear Bugman,
The California Mantis living on my Sweet Sarah clone is growing, but today was the first time I saw it with a meal, but these flies were swarming around and the Mantis was shaking its head and moving, but the flies kept pestering. I watched this for about a half an hour at which time the flies finally tired and flew off. What are they? I couldn’t see what the Mantis was eating, but it was green. There are lots of tiny Grasshoppers on my plants.

Dear Constant Gardener,
Your image is amazing. We quickly located this image on Colin Purrington Nature Photography that looks remarkably like your image, but the Flies are not identified, but they are compared to “vultures.” Then we found another image of a Mantis with prey and small flies on BugGuide where they are identified as Freeloader Flies in the genus Desmometopa and BugGuide states: “Females are kleptoparasitic and are especially attracted to predatory insects or spiders feeding on honeybees.”
