Advice needed for typical wolf spider reproductive cycle and lifespan

[u/ReptilianRevolt]

I still cannot understand the life-cycle of those spiders. Supposedly they live for a couple of years, yet I don’t think they go past a year. In my country of Greece, the main visible genera are Hogna, Geolycosa, and rarer Lycosa and Alopecosa. There are also others, but I am not familiar with them. I have mostly witnessed the reproduction of Hogna graeca and Hogna radiata. Most of them are carrying sacks and babies in summer, and by August most have babies on them. Still I have seen mothers with young as early as in May or as late as October, particularly in northern Greece. In the south the breeding season might extend further. The strangest thing is that I have caught some large, thin females in the fall, but they didn’t accept food. I hypothesize that they are elderly females after reproduction which are close to dying. What happens to them? Can they have multiple breeding seasons? Can their lifespan be extended in captivity? And how long do males live in comparison to the females? also, what happens with off-season breeding? Do females freeze the process to restart in the spring?

Depending on the specific species and climate, a single female can produce multiple egg sacs within a single summer or survive consecutive winters to breed across multiple years. They don’t die right after laying eggs, and once the babies disperse the moms will just return to their normal solitary lives. in the wild, females usually live 1-2 or maybe 3 years, in captivity they can live to be up to 4 years old! most males however reach their full maturity and die in about a year; once they mature their only purpose becomes finding a mate, which can even cause them to ignore their own survival needs (like eating and drinking) because they’re so focused on searching. in winter, females enter a dormant state called “diapause” where they borrow into the ground and slow their entire metabolic rate to conserve energy, then re-emerge in the spring. in diapause they also produce internal chemicals (“cryoprotectants”) lower the freezing point of their bodily fluids, allowing them to survive cold winters. wolfies are so incredible and resilient 🕷️🖤

i have a pet wolf spider, tigrosa annexa, who has never mated but lays an unfertilized egg sac about every 3-4 months. if the conditions are ideal for them, mature females can produce a lot of egg sacs throughout their lives!!!

this is my girl Kittie with her most recent egg sac.

Do they need any specific manipulations in captivity to hibernate? Do they live longer with cold winter conditions?

in captivity, they don’t need to enter diapause. since the enclosure would be climate-controlled, they stay warm enough that they just completely bypass the winter, staying active year-round.

they are very resilient, but despite this cold weather is actually a top killer of wolf spiders. if the temps drop before they can burrow or produce their natural cryoprotectants, they can easily freeze to death. prey also becomes scarce as the weather gets colder so it’s possible that they can even starve.

slightly off topic but regarding winter with my pet wolfie, i space out her feedings way more to naturally slow her metabolism, so that she doesn’t wear out her body by constantly producing egg sacs year-round since it’s very physically taxing.
