Hi * locality - Pa?l de Arzila - Coimbra - PORTUGAL * date - 2007.08.31 * size - 7 mm (medium fly) * habitat - swamps... * substrate - table.  I used a lamp bulb of mercury (130 W) to attracted some flies. I saw many keroplatids flies. I think this could be a Macrocera sp. but I'm not sure.EDIT---> Title changed from "Keroplatidae - Macrocera sp. ?" to "Keroplatidae - Macrocera sp." jorgemotalmeida attached the following image:  [172.91Kb] Edited by jorgemotalmeida on 14-09-2007 19:23 |

Impressive antennas, but perhaps not the most practical ... Why soo long? Are they super sensitive? |

Are they super sensitive? i really don't know if sensitive or something similar. but in Lepidoptera is a similar group (Adelidae family) and from what i know/i have seen that so long antenna have a role in somethinkga nuptial dance... so maybe similar??? just a presuption, cosmln |

I think these flies are more nocturnal, crepuscular. I realized that these flies have a slow flight. I only found these flies during the night rather the day. Antennas "(..)are primarily for smelling. So they have little or no tactile function(...)" as Theo Zeegers told before. Perhaps to find for food... they need big antennas in the darkness so they can easily find its supply of food. ? I really don't know why these flies have long antennas, I just appointed one possibility. It can be wrong. I would like to hear more opinions. Edited by jorgemotalmeida on 07-09-2007 18:54 |
