Bill W Posted March 6 Posted March 6 (edited) 15 minutes ago, sandrewn said: How Spiders Survive Winter is Cooler Than You Think Unfortunately, I was unable to view the video this link directed me to, but I looked up the following information: Spiders survive winter by entering a dormant state called diapause, seeking shelter in protected areas like leaf litter, under bark, or in soil, and by producing glycerol-based "antifreeze" compounds in their body fluids to prevent freezing. Many species die after laying eggs in protective, insulated sacs, while others remain active on warm winter days. Antifreeze Compounds: They undergo a process called cold hardening, where their bodies produce glycerol to lower the freezing point of their bodily fluids, preventing cell rupture. Diapause (Dormancy): Many spiders enter a state of suspended animation, significantly slowing their metabolism to survive with little to no food. Overwintering in Egg Sacs: Many adult spiders die in the fall, having already produced tough, insulated silk egg sacs that protect the next generation until spring. Indoor Survival: Common house spiders simply stay active, relying on the warmth of homes and buildings to survive. Active Survival: On warmer winter days, some spiders may emerge from hiding and can even be found moving on top of the snow, having survived in the subnivean zone (the layer between snow and ground). Shelter and Insulation: Spiders hide in spots that protect them from freezing temperatures, such as under logs, in rock crevices, deep inside wood piles, or deep within leaf litter, which acts as insulation .

Bill W Posted March 7 Posted March 7 18 minutes ago, sandrewn said: Armored spider (Perania sp.) Ok, I found this information as well: Perania is a genus of armored spiders in the family Tetrablemmidae, often found in tropical/ subtropical leaf litter or caves. These tiny, specialized spiders are characterized by heavy, sclerotized plating on their bodies, likely evolved as protection against spider-hunting wasps. They are distinct from the Idiopidae family, sometimes referred to as spiny trapdoor spiders. Key Details About Perania Spiders: Habitat: Primarily found in leaf litter, soil, and occasionally caves in Southeast Asia (e.g., Malaysia). Appearance: They possess a heavily armored, rigid cuticle, sometimes referred to as plated spiders. Adaptations: Some species found in caves have reduced or no eyes. Taxonomy: Belong to the family Tetrablemmidae, not to be confused with the unrelated Idiopidae family (armored trapdoor spiders). Discovery: Recently, five new species were discovered in the South China Karst. 1
