Spermathecae Resource Thread

[NMTs]

Lol I think I might have helped create a monster here lol. Next thing you know @NMTs Is trying to get time on the electron microscope in Albuquerque, talking about I need to sex this molt from a Cyriocosmus sellatus that went from EWL to 1i .

I'm sure they've got some pretty sweet equipment at Sandia National Labs, and that's just down the street...

I've always enjoyed the challenge of sexing T's, especially the small ones, so I've been thinking I should get a proper microscope for a while. You definitely got me to start looking seriously, though, because it's hard to even know where to start when you've not used a real microscope since biology lab in college (which was an undisclosed number of years ago ). Your list of suggested equipment was extremely helpful, so yeah - the bombardment of spermathecae pics is absolutely @l4nsky fault everyone! Ha!
