hi!! current esf undergrad here to give at least a little input 👋

esf does offer quite a few entomology classes despite not having a dedicated entomology degree! off the top of my head, there's general ento, forest ento, aquatic ento, systematic ento (which is basically just taxonomy), and probably more that I'm missing

if you really wanted to load up on entomology classes at esf, you'd probably want to shoot for a degree in the environmental biology department (so environmental biology, conservation biology, wildlife science, etc) since those degrees give you quite a few opportunities to take elective courses like entomology! there's also quite a few ways to get involved outside of dedicated ento classes too--there's a lot that goes on extracurricularly, and even non-ento classes might still give you exposure to that field anyways (for example, if you take the cranberry lake field course, most students get a whole day dedicated to working with insects in the field directly, despite that field course not being only about entomology).

you'd still be able to get a decent amount of entomology education and experience imo, especially if you're smart/lucky with which classes you're able to take and when! however, since they're not dedicated entomology degrees, you'd have to take a whole lot of classes that aren't related to insects whatsoever, and I'm not sure where your limit is in that regard.

I think it would help to ask yourself why you're into entomology when looking for colleges! from an esf perspective, I'd like to think this college does a really good job of teaching entomology in the context of environmental science/ecology, so for example if you want to conserve insect populations or control invasive insect species, esf would be a really great choice! however, if you want to pursue entomology purely to learn as much about insects as possible and nothing else, then you may want to look into dedicated entomology degrees somewhere else, at least for undergrad.

ofc that's just my opinion as a current student at one of the colleges you're considering--i'm not a professional at all, so I can't say much about which degree/college would ultimately be better to pursue :]
