hello, insect found today, 19-07 , Belgium, at a creek.. it really looks like Sepsidae, but it really isn't...four wings, wasp-like body,long antennas. But it was sitting here with spread wings just like e Sepsidae... Why would an insect mimic a Sepsidae? or is it the other way round? Anyone? thanks a lot..

Hello Chris, bums wrote: Why would an insect mimic a Sepsidae? why should it? or is it the other way round? Or it's pure accident? This insect has a rather general wasp like look (doesn't look more than superficially similar to Sepsidae to me). I think it's Braconidae or near.

Ants taste bad and (usually) sting. Sepsidae want to look like ants. Many other insects also want to look like ants. An Alydidae nymph or a black-winged midge in genus Chasmatonotus looks like an ant crawling on a leaf. They are not trying to mimic Sepsidae. |

Hello John, John Carr wrote: Ants taste bad and (usually) sting. hmm..., but by far most ants (the workers) don't have wings, and many ant mimicing insects or spiders also don't have wings (spiders, Nabidae or other true bug larvae) or no obvious wings (some true bug imagines, beetles etc.). Mimicing an ant with wings does not seem to make much sense to me - statistically...

thank you both  Juergen: I was asking myself the same, " why should it" . What was attracting my attention was the typical Sepsidae-like spreading of the wings...not just for me to take the pictures, but for minutes..just like Sepsidae do...in that sense I found it quite similar, let aside the general appearance... I noticed quite a few wasp and ant species the last year, but never this typical wing-spreading and again thanks .. Chris |
