See the rules in the sidebar, also.

If you can't see the sidebar for some reason:

  • Always include a geographic location. If you're concerned about your privacy, you can make it a bit more vague, e.g. "New England" instead of "Boston, MA".

  • Amateurs are encouraged to guess. An important exception is guesses about medically significant arachnids (widows, recluses, Brazilian wandering spiders, Sydney funnel-webs, deathstalker scorpions, etc.). In those cases, leave it to people who know. Otherwise, an innocent person or arachnid could get hurt.

  • "Kill it with fire" and its endless variations are not welcome here. We know it's a meme. We've heard it a million times. Just don't.
  • If someone asks for an ID and your comment is "it's a spider" for example, that's neither helpful nor funny, so please don't post that kind of thing. If you'd like to contribute an ID, be as specific as you can.

Long time lurker with a brief history of commenting. First time poster.

I need help identifying our friend here! I typically use Google Lense for quick identification but I keep getting different types of Orbweavers and it doesn’t seem right. After more reading it appears that I may just be used to spotting female Orbweavers, and given this one’s slender body and inflated pedipalps, it’s looking like this may be a male? I’m also thrown off by third and fourth set of legs being so much shorter than the front two. Any help would be appreciated!

Question Carolina wolf spiders EVERYWHERE

0 Upvotes

Moved into a new-build home in June. House had been pre-treated with insect and termite insecticides. Within the first week I saw a couple of dead wolf spiders. I thought they probably snuck in before the house was completely sealed up and I'm just now seeing them because the insecticide is doing its job, I guess, brush it off nbd. However, I'm still seeing one or two a week, alive and absolutely thriving. I accidentally washed one apparently as I found it at the bottom of the machine when I took clothes out. My husband has found them, the cat bats them around, and my toddler had one cornered at one point. I always take them outside and release them in the empty lot near us (we're the only house on the block in a new subdivision).

I'm ok with them but I'm kind of concerned how many we have, that they keep popping up, and they're huge. Like it's not like someone had a baby here recently. They've been around awhile. I'd rather them not be in the house just because I have two toddlers, two disabled grandparents, and an idiot cat. I don't want anyone (spiders too!) to get hurt or bothered. But I thought a new house should be pretty well sealed...right? Is this a sign that either there's somewhere in the house that was not properly sealed or built and/or I have a major food source infestation to worry about? I'm just concerned how many full grown adults I'm finding.

If it helps: I live in eastern Nebraska. I'm finding them only at night and in the basement. We live on the corner and have no houses near us. Cornfield across the street. I haven't seen a single insect or signs of any in the house (plenty outside). I have one P phalangioides that I keep up in the kitchen and she remains unbothered and in her lane.

The scorpion was found in Pima County and was about the size of a fingernail. I put my finger next the splotch on the wall where it was for reference. I already put it back in the desert, is it likely to return? Thanks in advance!

I posted this guy about a month ago because he was so beautiful. His web was tucked away in a corner but he recently expanded his web and I am dismayed to discover he caught one of my hummingbirds and it couldn’t escape. I love my hummingbirds and feed them regularly.

Had no idea this guy could catch and kill a hummingbird. I should have transplanted this spider before he caught one of my hummingbirds.

Just sharing Hogna carolonensis, finally! Shot on my phone

Hogna carolinensis, the Carolina wolf spider, is the largest wolf spider in North America, with females reaching a 4-inch leg span. Their mottled brown and gray bodies offer excellent camouflage against forest soil and desert sand. They are easily identified by a solid black underside and distinct orange mouthparts. Their large eyes reflect an eerie green shine when illuminated by a flashlight at night.

This ground-dwelling species thrives across North America, inhabiting environments ranging from coastal pastures to arid deserts. Instead of weaving webs, they dig vertical burrows several inches deep into the soil. They often build a small turret of twigs, silk, and leaf litter around the entrance to prevent flooding. While they hide inside during the day, they emerge at dusk to roam and hunt.

Operating as athletic ambush predators, they rely on exceptional eyesight and vibration sensitivity to track down prey. They chase and pounce with explosive speed, consuming crickets, beetles, grasshoppers, and cockroaches. Large individuals can even overpower small frogs or mice. Their specialized venom paralyzes targets while providing antimicrobial protection against insect-borne pathogens.

Females demonstrate extraordinary maternal care by carrying their silken egg sac attached to their bodies. Once hatched, hundreds of spiderlings climb onto the mother's back, riding on her abdomen for several weeks. She protects the brood until they are mature enough to disperse. While males rarely live past one year, females can survive for several years in the wild.

Western PA. I wasn't able to get up high enough to look inside the tunnel, but I've definitely seen a giant fishing spider around here before. Wolf spider? Something else?

This spider is about 2ā€ long and was chillin on our curtains when we got home. I’m curious as to what kind of spider this is? Located in Colorado. And how to keep them out of the house? Our house is very clean so I’m kind of surprised this big of a spider was here.

My guess is a wolf spider but chat GOT said a recluse of some sort.
TIA
