H. Mem. Sexing

[tphan]

I had what I thought were two male H. Membracenea nymphs (counted 8 segments on both).

One was an instar ahead, but the smaller one molted this morning and appears to have only 6 segments now. 

Can anyone verify the sex of this nymph with these photos?

Sorry I couldn't put them up on the site, phone picture size was too big.

The one in the photo is a girl. It can be hard to sex nymphs when they are young because they all start off appearing like they have eight segments. In females the end segments will end up forming into one as they get older, thus you can go from thinking you see eight distinct segments to six.

Well that certainly explains it. Thanks a lot!
