Any idea how long it takes until they are old enough to reproduce?

I dunno. The females take a few weeks to start laying eggs but both of the new adults are males and I wouldn't be surprised if they can start mating much sooner.


This lil guy hatched today!



And here's one of the males eating his first meal since reaching adulthood

No more eggs have hatched yet, but the 1st instar nymph is already looking pretty fat from eating a flour beetle larva and a baby dubia roach.

Molt!



Must say, I wasn't expecting the first nymph to molt before any of the others had even hatched... though fortunately many of the older eggs (there's now 23 eggs in total) are starting to turn lighter and swell up just like this one's egg did prior to hatching.

In other news, the last of the original 4 bugs molted to adulthood a few days ago, and it's a female. (More eggs!)

These guys have been pretty cool. I might have to see about getting them after I finish my planted aquarium.

Finally two more eggs have decided to hatch.



Meanwhile, here's the second instar nymph. Must be at least 5 times the mass of a hatchling already.

Update:


A total of 18 nymphs have hatched. Two of them hatched deformed because I let the container get too dry, one was cannibalized, and one died inexplicably. The remaining nymphs are all growing nicely, and that first one that hatched a while before the others is now a subadult. (And it seems to be bigger than any of the adults were when they were subadults, perhaps because I've been feeding it tons of nutritious dubias.)

Unfortunately I've been having some problems with mold killing the eggs, or at least growing on dead eggs. But the two females have picked up the pace on egg laying and I now find 4-10 eggs every morning! I call them "the hens" tongue

I didn't know cannibalism was a issue in this species?

Yep. But only rarely and with nymphs. They do avoid eating eachother, but I imagine it happens when one gets overly enthusiastic and grabs one of its brethren when lunging at other prey.

Just an update if anyone still reads this. There's around 25 adults and god knows how many nymphs now. The young nymphs seem to hatch in "waves" and there's been a fair amount of mortality in the older batch of nymphs (mostly adults now) because I kept them in an overcrowded container for too long and there was a lot of cannibalization and mismolts going on. I keep the l1- l2 nymphs in a deli cup with eggcrate, the l3-l5 nymphs in a larger plastic container with eggcrate, and occasionally remove larger, fatter l5's and put them in the adult enclosure to make space for new l3's. I only choose the ones who have probably already eaten enough to molt to adulthood because nymphs just can't seem to compete with the adults for food. There's this one female in particular, one of the original 4, who I recognize by her slightly deformed wings that's extremely aggressive. Despite the fact that I only toss in one or two roaches a night, she seems to be eating one half the time and has an incredibly fat abdomen.

I was actually thinking about getting some of these. Would you be interested in selling a few of the nymphs?

Sure! Does $5 apiece plus shipping sound reasonable? If you want I can throw in some eggs, an adult with a deformed wing, some Diapheromera femorata eggs and a Geolycosa missourensis wolf spider for free.

Yeah, sounds awesome. The Diapheromera femorata eggs would be super cool as well. I will PM you the dtails later. First I have to look into a good period for shipment as it's starting to get cold.

I think all of these guys would handle the cold somewhat well, although Im unsure
About the Platymeris biguttatus. Do you know how cold tolerant they are?

40 hours. I'll make sure they're well insulated so they'll stay warm if it takes longer. You can also have a the package held for pickup at a post office so it won't get left outside.
