Remember, pretty does not mean it doesn’t have a savage bite.

Today was the day I was going to try breeding a new generation of black widows. I gently introduced some males to some females, but then chickened out. No way were these males ready for the overwhelming majesty of a fully grown female.

That immensity is the female, on the left. The little guy on the right is a male, who I think is bit young for this exercise. He’s game, though, scurried right up to female and made a few tentative taps. It’s a bit like watching a mosquito getting the hots for a passing zeppelin.

I think I’ll have to tank up the males for a few more weeks.

Phase 1 was moving the young black widows to new, spacious quarters and giving them a day to get comfortable. Phase 2 is giving them a big meal so they aren’t hungry when meeting their beaus.

Here’s one female who has just been given a hearty breakfast.

The splotches near the center are spider poop, I’m sorry to say. I’ve been keeping them well fed, so they had to, ummm, relieve themselves immediately after the move. I dropped a large mealworm in this morning — it immediately scurried under the coconut fiber on the left. The spider was very excited, though, and has one leg on its butt, and although you can’t see it, has a silk line attached to it already.

I expect the ladies to be fully satiated and ready for love when I introduce them to some males tomorrow. Friday should be exciting!

This is one of the black widow females I just moved into roomier quarters.

It does not have a red back. Our North American widows are a solid black, with a red hourglass on the underside of the abdomen.

This is one of the males, currently separated.

Seriously dimorphic, which is why he won’t be introduced until the female is fed again, and I can keep on eye on her shenanigans.

An Australian reader sent me this photo of a redback, the Aussie version of Latrodectus. So pretty! And with an egg sac!

That reminds me…this is a big week in the lab, I hope. My second generation black widows are looking ready for breeding, so that means I have to prepare the nuptials. I’m moving the females to a larger, cleaner container and giving them time to make a cozy web today. Tomorrow I’m giving them a feast — gotta fill ’em up so they aren’t hungry when a visitor comes calling. Then on Friday I’m introducing them to second generation males.

I’m a little nervous about that. As usual, males are less common than females — more of them die during development. But the big concern is sexual dimorphism. Latrodectus males are so much daintier and distinctly tinier than the females, so it could be a bloodbath in two days. I’ll record video of the event, and maybe if it isn’t too disappointing I’ll post it then.

I walked down the road to the mighty White River, a fast moving stream that descends from the Cascades carrying a load of glacial silt, which is how it gets its name. I had to stop and take a photo.

That lucky spider has that view 24-7.

I came home this afternoon to find swarms of dispersing spiderlings — the trees and shrubs were dotted with these tiny little guys on skeins of silk trying to spread out and find new homes.

It’s October, you dopes. It’s getting cold (although this week we’re having a surge of warmer weather), it’ll snow sometime in the near future, unless you’re looking for a safe place to hunker down and overwinter, this doesn’t seem like a smart strategy to me.

I found a nice big orange spider last night. Halloween is coming!
