A new thread to bring together those flies that mimic other species of insects.
This specimen gave me this idea, I would have bet it was an Hymenopteran

See: Loxocera hoffmannseggi (Psilidae)

It looks like it is mimicing an Ichneumonid.

See: Bumblebee mimic
Merodon equestris, Syrphidae, note the way wings held across abdomen, typical of bumblebees.

Several Syrphidae e.g., Temnostoma spp. such as T. bombylans and T. vespiforme mimic wasps, the latter species mimics Vespula and Dolichovespula spp.

I think for social wasp mimics, the tephritid genus Bactrocera takes some beating - see

Milesia crabroniformis (Syrphidae) mimics Vespa crabro (Vespidae).

This is a North American Physocephala sp. (Conopidae) that closely resembles a Potter Wasp (Hymenoptera: Vespidae: Eumeninae). In fact, when I first saw this fly on a flower I thought it was a Potter wasp.
Length: 10.5mm excluding antennae. 19 September 2007, New Brunswick, Canada.

Tabanidae, Hybomitra zonalis, female. 9 July 2005, NB, Canada. Length: range 14-18mm.
Black and yellow banding is quite common in many insects and is thought to be seen as a warning pattern to vertebrate predators. Black & Yellow banding, of course, is the basic colour pattern of stinging wasps which presumably form the model for this and the other wasp mimics.

... and, of course, the "Drone-fly" (Eristalis tenax), whose model is the honey bee drone. In this photo the similarity is amazing:

C. vespiformis is very similar to Conops flavipes. But here it is convergent evolution, I think.
Both mimic wasps.

Sepsidae flies have an appearance similar to some ants.
But I think this is another case of convergent evolution. Am I right? Anybody contests this assumption? Thank you.

Anything that runs around on the ground or on leaves and looks like an aggressive venemous predator has my vote for a mimic.

Need a photo of a Rhagoletis from behindGrin
According to Marshall "the wing-banding pattern....seen from behind.. makes the fly look remarkedly like a jumping spider (the bands look like spider legs)"
Who wants to tangle with a jumping spider?

Edit: Further reading indicates that the mimicry is to fool jumping spiders as these spiders are the major predators. "Greene et al. (1987) and Whitman et al. (1988) showed that Z. vittigera mimics jumping spiders and is significantly protected from these common predators on its host plant. During the fly's wing flicking displays, its wing pattern resembles the legs and the abdominal spots the eyes of a spider in its own territorial display."

Several Asilids in the genus Laphria are mimics of bumlebees, e.g., Asilidae > Laphria affinis (male)

I think we can put this in the same league as the "Alligator Bug" (Homoptera: Fulgora laternaria), the head of which does look like an alligator and would be great mimicry apart from the discrepancy of habitat and size between the model and mimicShock.
