If you’re into beetles, check out the Cerambycidae family, better known as longhorned beetles. They’re a huge group in the insect world, with about 20,000 species already named around the globe and plenty more out there waiting to be found. You’ll spot them on every continent except Antarctica.

What makes these beetles cool is their big size, wild colors, and textured bodies, which actually help make them pretty easy to ID, even with around 1,100 species in North America (not counting Mexico). This guide plays off those traits to make spotting them straightforward for anyone interested.

It comes loaded with more than 600 color photos and covers 342 of the 344 known species and subspecies from northeastern North America. You’ll get the key details to tell them apart, plus info on where they live, when they’re active through the seasons, and what their larvae like to munch on.
