Hello, It seems that my mating couple doesn't call for comments. This afternoon, I saw one of them (still the two whitish hair strips in the eyes and the two whitish bands on the thorax). pierred attached the following image:  [105.77Kb] Edited by pierred on 08-05-2006 17:48 Pierre Duhem |

Hello, Somebody told me on another forum that this sould be Paragus sp., maybe Paragus pechiolii (ex P. majoranae). Well, taking M.P. van Veen's key from the Paragus genus, I follow the key : 1.b. Eyes, pilosity distributed in bands, scutellum black or black with yellow tip --> 4. 4.a. Tergites without yellow bands but black or (partly) red, generally with silverish bands of dust... thoracic dorsum: dull with 2 stripes of dust. --> 5 5.a. Head in side view: face somewhat protruding, scutellum often with yellow tip --> 6 6.b. Tergites 3 and 4: bands od silverish dust well-defined (figure 549 = P. pechiolii) Is this somehow correct? Thanks for your comments. Please be kind with me, it's the first time I use a key. Pierre Duhem |

Hello pierre, Yes, it is quite correct! It's indeed a Paragus species, and if you follow the key coorectly you will indeed end with P. pecchiolii! So, no need to worry, you did quite well! Greetings, Greetings, Gerard Pennards |
