This is a French Guianan bombylid photographed by Stephane Brule - can it be identified?

Oh itīs amazing! I hope anyone can identify it, just a few "lost steps" looking drawings of books - the most similiar wing at Palaearctic seems Exoprosopa pectoralis, it has yellow face but black frons :( (Engel, 1938) - another similar wing pattern: Diatropomma, related to Isomyia but both have a narrow wing base and are Etiopian :(( ("Exoprosopinae", Hull, 1973) - at bugguide: http://bugguide.n...96/bgimage - page 159, figure "f" Poecilanthrax http://redalyc.ua...523111.pdf - "nearest" ones in keys for eastern (US) are Exoprosopa and Dipalta Could "Exoprosopini" be said at least? :( regards :) Edited by paqui on 19-10-2011 22:18 |

This is Hyperalonia morio ssp. erythrocephala (Fabricius). Great shot! -Neal |

There are several taxa of Neotropical Stratiomyidae with similar colouration. Does anyone know whether this is mimicry of some kind, and which could be the supposed models? I cannot remember having seen stinging aculeates in S-America with such colours... |

Great shot! -Neal Many thanks Neal - all credit for the photo goes to Stephane Brule in French Guiana As Menno says, the coloration (with the bluish ground colour and yellow head) does remind me of a few of those stratiomyids that are common in the same region - Cyphomyia? Here is another of Stephane's photos (of Cyphomyia):

Yes, those are the ones I mean. And if I remember correctly there is also another (unrelated?) stratiomyid genus looking like this. Of course there doesn't need to be an aculeate model: if one or more of these flies just taste very bad, they may also benefit from looking like each other (Mullerian mimicry or a combination of different types of mimicry...) |
