Hello, Please, can comeone help me to identify this fly (or even spider)? Size: cca 2.5 mm? Habitat: light forest with oaks, cherries and black locusts Slovakia, Kosice, 300 m a s.l., July 2005 Spider prey is probably Formica sanguinea. The fly seems to be very impertinent, it feeds literally from spider mouth,  . The situation is also here: http://www.fotoaparat.cz/index.php?r=25&rp=209911&gal=photo Thanks for any ideas.

The fly is a chloropid of the genus Tricimba. I have seen such behaviour in Desmometopa of the Milichiidae, but never in Chloropidae.

Thaks a lot Paul! I have also seen various flies in the vicinity of spiders with prey but this situation was very strange for me. In my photos there is probably also Desmometopa sp. on a honeybee attacked by the wasp Vespula germanica - I will sent it later. Martin |

Desmometopa are very 'fond' of honeybee preys of spiders, robberflies and reduviid bugs.

Thank you Paul for additional information. I am sending a Desmometopa (as I guess) in next thread. Martin |

Hello! Because nobody mentioned the spider: it's a crab spider (Thomisiidae) of genus Xysticus. Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |
