Hello! This male St. Marks fly just found on the wall of our house (Ostwestfalen/Germany). It was bigger than B. johannis, but somewhat smaller than B. marci I think. Can the species be determined? Thank you? Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

This is either B. marci or B. hortulanus. Hortulanus fits your description best. Characteristic are the light hairs on abdomen and usually also partly on thorax. The females are completely orange, quite easy. Theo Zeegers |

Hello, Theo! Zeegers wrote: This is either B. marci or B. hortulanus. Hortulanus fits your description best. Thanks! But the problem is: I have never seen an orange female here over the years. Yesterday afternoon not only the small B. johannis were flying, but now also many Bibio (cf.) marci males and some females. All completely black (and slightly bigger than the above one), except one female with reddish legs (B. lanigerus?). The links below are pics from 2005 (with my own unprofessional identifications), but the recent animals look quite the same: http://insektenfo...en_004.jpg http://insektenfo...la_001.jpg http://insektenfo...en_001.jpg http://insektenfo...en_004.jpg http://insektenfo...en_006.jpg http://insektenfo...en_001.jpg http://insektenfo...la_001.jpg And one from May 2003. Is this Dilophus febrilis? It was only half the size of B. marci. http://insektenfo...e)_001.jpg Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Hello! Today all Bibio species seemed to fly simultaneously in large numbers here in Germany :-). The most cute looking are the females with the red legs: Edited by Juergen Peters on 06-05-2006 22:48 Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

Hi Juergen, You are right: The larger male is B. marci, given the new pictures. The Dilophus febrilis is correct (a female: wings very dark). Theo Zeegers |
