Stilt Legged Fly

Hi Dee,
This is a Stilt Legged Fly in the family Micropezidae.  According to BugGuide, they are “Odd little flies, known for their displaying (?) behavior of walking around and lifting their prominently marked front legs. Abdomen attached to thorax by “wasp-waist”. Likely ant or wasp mimics. The posture of the forelegs may imitate ant and/or wasp antennae and provide them with some protection from predators (speculation–Cotinis).
”  We will leave species or genus identification for an expert in the field.

  1. We have quite a few of these in our house, they seem to be coming out of an A/C vent. We can’t find any leaks in the duct work. How can we stop the invasion?
