From my garden near Copenhagen, Denmark may 21, 2009. I´ve called it Xanthogramma pedissequum and first now been aware of X.stackelbergi/dives. Thanks in advance Ruth Ahlburg attached the following image:  [146.3Kb] Ruth Ahlburg Denmark |

Yes, should be pedissequum, but the two other species are difficult to separate from another. Greetings Greetings, Gerard Pennards |

What made me doubt pedissequum was this link: http://www.tam.pp...gramma.pdf. The menbrane between tergites and sternites on abdomen is all yellow from the end of tergit 2 and distally on picture 2. But I can easily be wrong, of course. Kindly Edited by ChrisR on 21-08-2010 23:53 Ruth Ahlburg Denmark |
