Can anyone advise on ID for this one. Observed in Parc national du Bic (Quebec, Gaspesie) on June 8th. Approx 8 mm. Clearly abundant on the tide mark algae on the beach. Thanks for your suggestions Philippe Philippe moniotte attached the following image:  [75.78Kb] A beautiful hypothesis can be slain by an ugly fact. |

I guess Sphaeroceridae?!

Looks more like Coelopa to me. The first tarsomere of the hind leg is longer and no thicker than the second, which is very unusual in Sphaeroceridae. |

Thanks all, How about Coelopa cf frigida ? A beautiful hypothesis can be slain by an ugly fact. |

Sorry, I only had a quick look at the wing venation and general appearance and that was consistent enough with Copromyzinae...
