I just adopted a spider but I don't know anything, help

Hello, a few hours ago my cat was close to eating a wolf spider in the yard but this spider is a bit big (4cm) and well I saved it and I liked it, to the point that in minutes I had an improvised artificial burrow ready for it, I investigated and I made sure I met the requirements but I don't know how to feed it, apparently moths and mealybugs are not a very good option, so to speak, I don't know what other insects to feed it, it only comforts me that they eat every 3 or 4 Hello, any advice I would appreciate, by the way it is a male spider.

Extreme Roach Phobia, therapy didn't help, need motivation or tips that helped anyone

I have intense fear of roaches since childhood, it is only getting worse. I could handle the sight of one, like 5 year ago and be in the same room until someone else got it for me. Now, I can't even handle the sight of one, and would ask someone to come up to my place to kill it, or if it is not feasible, I would leave the apartment and potentially consider moving. I can't even look at a picture without feeling extremely anxious to the point of getting physically sick. I had to move to a new country and specifically chose one with colder weather than tropicals where there are more common. Turns out I spotted one last night and screamt and cried while couldn't even being able to get close , and hid my self in the bathroom for hours. Please help with any advice that has helped you, or what you think might.

Hey Entomologists!

What are some understudied insect groups that need some loving. I'm located in the Northeast U.S. and would love to contribute to some research while in school.

Beautiful intact specimen!!

This Unicorn Darner dragonfly died very recently on the front step and I was so lucky it’s intact! No missing legs or wing/abdomen damage either. Also not a species I see a lot in my area, much less expected to find a fully intact specimen of!! I am debating a simple frame or creating a more elaborate glass dome display for it based off a lake’s plants. (Reeds, dried aquatic plants, perhaps a rock or thick stick to act as a ‘perch’)

Who is this little rascal?

I see these guys when I clean one of the bathrooms in a building I work at. They're very small, smaller than my pinky nail. They tend to just sit still but they fly around if perturbed. I don't think I've seen them anywhere else before but I'm not sure. I think they're sorta cute, they're like flies with bunny ears. Anyways, I hope you fellas can help me put a name to this face. :)

Is this derpy guy a stink bug?

He also flew right on me when I tried to gently move him off of my ceiling with a broom and he gave me a massive heart attack❤

Spiders teamwork

Greeting from Chile, I recorded this two Steatoda nobilis wrapping this Bombus terrestris. What's amazing is that they appear to be working together, they are usually quite agressive to eachother but in this case it looks like a coordinated attack.

Slate millipede help

How long do they live? Are they easy to keep? They're native in my state and I have clay like dirt in my backyard which I heat treated, some mesquite wood that was dead on the ground, I double heat treated that. I am going to buy leaf litter and cholla wood as well. I really love these guys and I'm trying to make sure I know as much as possible.
