My grandson is planning on studying entomology and I know exactly what you mean.
He loves creepy crawlers and always has. My son-in-law had to stop him once while they were hiking, and he headed toward a snake that Matt knew was poisonous. Wesley was only about 7 when that occurred.
He has quite a collection of bugs and when he comes to Florida, I can depend on his locating most of the little chameleons in the yard. He's very kind, though. He never kills anything.
One thing here that I do really like are the tree frogs. They never bother anybody or anything, but eat LOTS of mosquitoes.
Yes,some of those critters look like they're from outer space. LOL
