Wanna feel my palps? Said the HE to the SHE. This is a Spider Sex Story 😱


Wanna feel my palps?  Said the HE to the SHE.  

My husband said this title was far to risque’ but I’m going with it anyway.  I would tell you to “get your mind out of the gutter,” but this is a SPIDER sex story.  Sex education is not a bad thing and it’s good to know how it all works, right?

So male spiders have these fuzzy, enlarged “paws” that sort of hang down in front of their face.  People who study spiders call them palps.  They are sort of like a 5th pair of legs, but used by the spider to manipulate food and “smell” things.  These palps are also where the sex organs are housed in adult male.  The hairs on the palps have chemoreceptors that help the fellas follow the pheromone trails of SHE spiders.   This is the mating season for one of our commonly seen spiders in the San Juans…the Giant House Spider (Eratigena duellica) who happens to be harmless, just horny.

How do spiders DO it?  Well, an adult male spider will weave a small silken sheet called a sperm web.  He deposits a drop of semen on the sheet and then dips the tips of his palps into the semen, drawing it up into what is called the emboli.  The emboli act like a syringe, drawing the fluid up to be held in the palp for transfer to a SHE spider.  With his palps “charged and loaded,” he gleefully wanders off to woo all the ladies. 

Some of these male spiders really go all out to impress a gal.  They will drum (with their palps), dance, and display all sorts of postures to show how great they are.  They better do EVERYTHING they can to impress her too since SHE might eat them if it’s not good enough. Watch a jumping spider perform his quirky courtship ritual here –

If mating is successful, the male usually makes his exit…quite literally.  He’s at the end.  

And THAT, my friends, is the end of this spider sex story.
