Phimenes sp.

hahaha :-) nicht so oft gesehn...aber wenns mir mal wieder unter die finger kommt check ich die Größe

Auf die Grösse kams doch noch nie an ;-)... Ich habe keine andere Art gefunden. Check doch die Grössen nochmals...

i might ask some thai people for the common thai name

thanks bayucca. the genera i think is correct, but i doubt the speci. This was really 3,5 cm or longer.

who cares about common names?! :)

Vespidae, Eumeninae, most probably Phimenes flavopictus. Please, verify and specially verify the uncommon common name, you never know ;-)...
Other common name would be Potter Wasp.
