Featured here is a stilt-legged fly. This species look remarkably similar to ants, but the photographs don't do the mimicry justice.
The fly was on a leaf and didn't keep still for a second, and hence was difficult to photograph.
I however did manage to find focus on its long ovipositor which was retracted beneath its abdomen.
I`m not sure what the purpose of this mimicry is. If you do, leave a note in the comments.
