Danny Wolff's site gives a lot of that kind information. Habitat, flight period etc. It is very useful.... it also shows that your specimen is very late : ) M rusticus is known to be a fly from warm dry grasslands, in NL it is only known from the southern calcareous grasslands. I don't think it is entirely what you are looking for but, together with André Schulten, i made an online photo guide which contains as much info on behaviour, habitat, flightperiod...in as little text as possible (in Dutch):http://waarneming.nl/download/fotogidsAsilidae.pdf A next step might be a matrix key including habitat etc....
