Hello , I have a collection of fossil wasps, mostly in Amber, (Burmese ca,100MYO and Baltic ca, 40 MYOetc) , in Burmese amber I have a specimen of (Crabronidae, subfamily Mellinae genera ? Mellinus).. this is a Cretaceous wasp and must have flown at a time when Dinosaurs roamed the Earth. Would this wasp have visited dinosaur dung? was it a vector of disease? and what did it prey upon? .... I am not an entomologist and ''come at'' wasps from a palaeontological angle ( I study wasp wing venation in my fossils..i think this is called HORSIMOLOGY?)... ANY ideas for ''fossil'' behaviours of a 100 Million year old Mellinae ? ...thank you
Mark.
