While I'm not exactly new to invertebrates and natural history I have to admit I dont know a great deal about true flies.(I know that Diptera means two wings, thats about it!)
I have a Collins Guide to Insects which is like a generalised overview of most species to be found and I suppose I could read the section on Diptera to get the basics but whats the best source of information on the group? Nothing too technical though I can handle works that seem quite technical to the layperson. I have studied spiders for quite a while so am familiar with their anatomy and physionomy but I'm guessing Diptera would be a totally different kettle of fish!
I have lots of questions such as how many families are there, and how many species? How widespread are the species I'm likely to find here in the UK? And how do you sex Diptera? Also how do you pronounce Diptera? ;) Is it Dip terra or Dye terra?
Thanks for any info guys!
