Thick-headed Fly (Physoconops sp)
Another one of the wasp-mimic flies, most thick-headed flies resemble thread-waisted wasps. Adults visit flowers and feed on nectar. Larvae are internal parasites of bumblebees and various wasps. The female Physoconops is said to lay her eggs on host species while in flight. The eggs hatch and bore into the host which they consume from the inside out.
