Perhaps we should just expand on the glossary? More pictures there would be useful and fairly easy to do. Entries like "wing venation -calyptrata" or "wing venation - brachycera" could have accompanying photos/diagrams of wings. I noticed "petiole" (a common question with calyptrates) doesn't have a diagram. Maybe Paul can arrange this when he is back? He is welcome to use my photos here and I'd be happy to improve them is anyone has any suggestions. :)
