I never saw an Usia so lately! Usually they are early species... |

This one is from the end of July. I guess that high in the mountains they come out later. The flowers up there flower later and this year they were particulary late. |

These appear to be typical of the taxon i call Usia aenea, however, U. similis is unknown to me and probably very similar. |

I thought this would have been a different species than a previous U. aeneus I published here. I think it was a bit smaller, and seems to have fewer white hairs on the torax. Also, the black markings above the light ones at the base of the wings are more marked. Although, I could be wrong. Thanks, Guillermo. |

Thanks, Guillermo. do you mean this one?. If so you are possibly right, the one in the gallery does not look right for aenea. However, aenea as i currently understand it is highly variable and possibly a complex of sibling species. |

Yes, that is the one I meant. Reading again, I noticed I was not very clear. The smaller ones with fewer white hairs are these later ones on the yellow flower. I guess that is probably why Miguel Carles-Tolr? identified the one in the gallery as U. aenea or aenoides. |
