But where does it keep it?

Drag queens

That’s one way to reinforce the patriarchy

Sequential hermaphrodites are like: ‘I’m the largest so I guess I’m male now.’

Prickily pricks

Scratching that itch

I’d attack anyone who came across me while I was licking my vulva as well.

Gender reversal

‘Give it to me’ has a new meaning

The nutrients are extra valuable in such a dry environment, creating a situation where females compete for males. I’m not sure why this would have driven the development of the gynosome- maybe the more females could insert themselves into the males the more successful they were.

Seeing the Light

Is it in?

Dr. Arikawa was working on sensory stimuli of Japanese yellow swallowtails when they discovered that the butterflies have light sensors on their genitalia. They have since found similar light sensors on a number of other butterfly genitalia. Also, I’m not an expert, but it appears the male butterfly in this image is hanging from his dick.

#1 DAD

So many limbs, so little anything else

My original post was kindly corrected by Dr. Bonnie Bain, who pointed out that the secretions- mainly emitted by cement glands on the femurs- the eggs were wrapped in were probably not mucus, but no one has investigated the material in depth. Dr. Bain’s paper has a lot of other interesting details about the mating of the sea spiders (pycnogonids), including some fascinating descriptions of courting behavior, and aggression between females for mates.

Needlessly complex

There is a LOT of debate about why genital structures are so varied among species. SO MUCH DRAMA.
