Hey dipterists I've got in a same sample 4 S. larvae I wish to go ahead in the ID... I know I have already, thanks to Atylotus, Oplodontha viridula Here is a picture of the 4 larvae, respecting their dimensions I guess that the biggest one (35 mm) will be Odontomyia My question is "are the pattern of the cuticule something usefull to ID ? As visible nr2 has a short white strip on the thoracic segments, the 4 th one a long white strip over all the segments  merci SDS Edited by solito de solis on 19-04-2017 12:40 |

for short: yes it is usefull longer version: I have a theory that color pattern differ in each species but probably also differ within a species. I think that each species has 2 different color patterns and propably (not proven yet) these are related to male and female larvae. At least 2 color patterns exist withing O. viridula and I was able to breed few and indeed the females had another colorpattern than males, but this is not enough prove. Any help in this is appreciated. The large larvae (1) is O. ornata, no. 2 and 4 are both O. viridula and 3 probably Od. tigrina juvenile. |

Thanks Atylotus I will observe better now and make the best with your infos I make a profit with this topic to put a few pictures about the Stratiomyidae cuticula from an exuvia found in the sample I could observe this like transparent glass or cristal parts on a dark skin The reason for the small reflections when the larva is observed... The color and the pattern of the cuticula are seen through these transparent pieces    profil

Any help in this is appreciated. Adler, Currie, and Wood (2004) mentioned sex-specific color patterns in larve of some North American Simuliidae. |

Hey dipterists Here is a smart videoclip showing closely the pattern mosaic-like appearance of these larvae (and more) https://www.youtu...e=youtu.be YouTube Video Edited by solito de solis on 30-04-2017 11:56 |
