I tried. I put the young male spiders with the young female spiders, and the females cringed and refused to move while the males wandered around pretending to be busy. You don’t even have to watch the movie, the full story is in the title.
I’ll plump them up and try again in a few weeks.
Look who was hanging out in our dining room:
Salticus scenicus
In case you were curious, here’s the boring routine for maintaining a colony of cute little Parasteatoda juveniles. Teenagers! Always demanding your time.
Right now I’ve got a sink full of dirty spider containers. I’ll have to get those cleaned up this week.
Always good for a laugh.
Which reminds me…yesterday, my wife tried to cheer me up by telling me she saw some small insects in the house, which means the return of the spiders can’t be far off. This seems to be an unusual response by most hu-mans.
I’m kind of laid up from a fall yesterday, having trouble getting any sleep because any turn of my head sends alarm signals up and down my spine. This is cramping my plans. I have a spider agenda! I need to move all the spiders, especially the lady spiders, to shiny clean new containers, so they can spend the next week getting comfortable and filling it with new silk. They won’t know it, but they’ll be making their nuptial bed. Yeah, time to try breeding! They’re still on the small side, so they’re comparable to human teenagers, but we’ll see if they’re as horny as people get in their youth.
I still have concerns about species matching, though. There are two spider species, Parasteatoda tepidariorum and Parasteatoda tabulata, that I can’t tell apart, short of dissecting their genitalia, which absolutely ruins them for mating, and I don’t want to put P. tep together with P. tab, since that could just end with cannibalism (wait, different species, so not cannibalism? Just violent murder?). My solution for this go-round is simple: I’m going to put male spiders on their sister’s nuptial bed. I want an inbred line anyway.
I’ll try to record their activities next week, so maybe I’ll have a movie for you then. With any luck, it won’t be a gory murder/horror flick, but instead a little incest porn. I hear that’s popular, but have no idea why.
Ooh, that was nice. I just relaxed with the spiders this morning.
Poking around in the weeds as we do every summer, looking for spiders, one thing we turn up a lot are frogs. Big frogs. They like to nestle in some nice shady leaves during the day, and we occasionally part some leafy foliage to find a frog looking back at us, as if wondering how dare we intrude on his home. I’ve often thought they need a good predator to teach them a lesson.
Like a clever huntsman spider.
Retreat and predation event near retreat of Damastes sp. (a) Spider specimen of Damastes sp. (THC140, adult female), the prosoma and opisthosoma are approximately 1.5 cm in length (smallest square = 0.1 cm)—Observation 1; (b) Damastes sp. feeding on Heterixalus andrakata (frog) inside of the retreat, built of leaves of Tambourissa sp.—Observation 1, (c) Predation event where Damastes sp. captured Heterixalus andrakata near the retreat—Observation 1; (d) Damastes sp. hiding in the retreat, built of leaves of Cedrela odorata—Observation 4
These cunning ambushers from Madagascar use silk to stitch together a few leaves, making a nice shady refuge that might appeal to a frog looking for respite from the daytime heat. The frog snuggles in, not noticing the large-fanged venomous arthropod lurking in the back, and then snicker-snack, he’s a juicy piece of meat being sucked dry by Damastes.
I don’t know about you, but if I poked my face into a local bush and saw a big glorious spider instead of a fat frog, I’d be delighted. It’s not likely, though, since our harsh winters tend to kill off most of the spiders, giving them only a short growing and breeding season.
Maybe this would be a bright prospect from global warming? Do you think Republicans would be even more resistant to the idea of good legislation if they thought climate change would create a better environment for big hairy blood-suckers? They do have some things in common.
It must be convenient to be a spider at Halloween. To decorate, you just rummage through your closet and pull out an old molt — instant skeleton!
The good news, too, is that my latest generation of spiders are growing up, and starting to molt. Here’s a shed spider cuticle I found today.
They shed by popping open the top of their head, which you can see at the top left, and then back out, pulling their legs up out of the old limbs. I keep hoping to catch them in the act, but I think they do it in the middle of the night, to minimize the danger while defenseless.
I put a picture of her post-molt down below.
Now you can! I saw that I can easily visualize the hearts beating in my baby spiders.
It made me think of those Pro-Life Across America billboards that show a picture of a cute baby and declare “My heart began to beat at 18 days!”, as if that was a significant event. So I take it anti-choicers who see this video will forever after be kind to spiders?
I spent a pleasant morning with the spiders. Look how quickly they snap up flies!
Today was a big spider maintenance day. I’ve got three lines of spiders I’m raising — R (from a spider collected at Runestone park), H (from the local Horticulture garden), and M (from the Myers garage) which I’m trying to bring to maturity, so they’re getting lots of food and care, which I want to start inbreeding and generate 3 lines of related spiders so I can start assessing their variation…and then start cross-breeding. It’s going to take a while.
Anyway, down below the fold is one that’s definitely male and might be ready for mating after the next molt. His palps look painfully swole.
