Photographed in southern Spain May 2014. Arid area with fruit plantations. Edited by Ratatoskr on 10-11-2014 01:17 Belief is not an idea that the mind possesses but an idea that possesses the mind. |

In the social Vespidae, males are distinguished from workers by an extra segment of the antenna and abdomen, and the tip of the antenna is often curved. Queens share the longer abdomen. Eumeninae are not social. Possibly all females are built like queen Vespinae and Polistinae. Hymenoptera that transport food are female (including workers). Transported food includes pollen (bees), caterpillars (Vespidae), flies (Crabronidae), and more, but not nectar. A wasp that is eating on the spot could be male or female. |

If you can count the number of "abdominal" segments, you can tell males and females apart. 6 visible segments = female, 7 segments = male. (For me, the picture is too dark.) Regards, Henrik |

I think I can count 7 segment, If this is correct, then it is a male. |

Regards, Henrik Thank you Henrik, Do males of all Eumenidae species have 7 segments and females 6? Here is a new enhanced photo of the abdomen. To me it seems like it's 7 segments. Am I right?

John Carr, Thank you very much for your information on differences to look for and note. I have written a small document with your information. Will add what Henrik said too to it. Interesting to learn this
