Posted to ask a question: does the tip of the abdomen indicate sex in crane flies as it does in dragonflies?

Sex determination
Generally speaking, the answer is yes. If you enter the code tipgs in the BugGuide search window, this will bring up thumbnails of the dorsal view of each of the crane flies that we have submitted. The several images linked to each thumbnail will include detailed views of the genitalia. Gender is also indicated for each specimen and I think the pattern of sex differences will become evident. Dr. Chen Young has suggested that a ventral view is most useful. We try to provide top, bottom and side views if possible.
Fine photo!
