Are you sure?
Can you tell its a female and not just a male without a genital bulb? If you can let me know how because I don't know and I'd like to :)

 
male without a genital bulb?
never crossed my mind... chewed off? what a horrible scenario...

 
Haha
Straight from Dan Young's mouth in Intro to Entomology "Just because its doesn't have a big genital bulb doesn't mean its a female." We even had it on an exam as a trick question. It didn't have a bulb, and the question was what sex is it, and our options were Male, Female, or Can't tell and the correct answer was can't tell.

 
i had no clue!
i checked the fam. decsr'n in (1) -- it cites the male bulb as the first character, no exception stipulated; same in (2)

 
Interesting
I wonder who is right... the professor or the books? :-P
