Well as that old song goes…

Let’s talk about sex, baby… and the bad things that may be…¹

you would think that lyric could have almost be written for the world of spiders, where if it was good, or if it was bad, the male could end up as dinner…

In the following photos, it did look like a risky manoeuvre by the male Golden Orb Weaver, being at the jaw end of the female Golden Orb Weaver. It was a slow, deliberate careful move (not sure if there were any pheromones being emitted).

Sex Organ of the Female Golden Orb Weaver Spider

For those who did not know, the sex organ of the female Garden Orb Weaver Spider is on the ventral (underside) of the spider, near where the head and thorax join the abdomen (opisthosoma). The sex organ is known as the epigynum (female genital opening). At the bottom end of the abdomen (also on the ventral side) is the spinnerets (silk spinning organs).

In the following two photos, the small male was disturbed by my hand touching the web. The male was originaly on the epigynum (arrow 2) before I scared it off her. You can also see the spinnerets (arrow 1).

In the following series of photos of the same two spiders, the small male was at the end of the female’s abdomen (where the spinnerets are). Currently not sure what he was checking out.

In the following series of photos, the tiny male is strategically positioned on the underside of the female (with the food pantry line in between).

Now we must mention the “sexual size dimorphism” among the male Golden Orb Weaver Spiders. Not all male Golden Orb Weavers are small. Check out our page on the Dimorphic Males and see the size differences of these males. So does bigger mean better… the jury may be out on this, but we do know the large dimorphic males would make for a better meal.
