The iNaturalist app is pretty good to at least get you a family or genus at minimum. It works for plants, animals, bugs, pretty much anything. I once used it to identify some pink foamy caviar looking stuff, which it identified as snail eggs.

A casual place for Arthropoda.
Submission Examples:

Rules:
- Relate posts to Arthropods.
- Note if an ID is keyed or a guess.
- If bit/stung, get medical help!
On this, I really like seek (an app by iNaturalist) for plants and the like.
The Peterson first guide to caterpillars of north America is easy to use and compact for travel. Obviously just does caterpillars pupa and moths/butterflies
This one is very easy to use for identification, a little bulkier but still could fit into the side pocket of a backpack. It is not great as far as learning a great deal about the bugs, but you would at least know what it was to look it up later.

Thanks for the suggestions! I actually found the National Wildlife Federation field guide like two or three weeks ago and it’s been helpful. Do you think there’s a significant difference? I’ll definitely try to get my hands on the other book you recommended too.
I haven't tried the NWF one, but i bet the NAS one is at a library nearby
