Moved from Field Crickets.

Moved from Grasshoppers, Katydids and Crickets.

You have a fine adult male specimen of genus Gryllus, the field crickets, and given your location and the time of the year, this one is most likely to be Gryllus pennsylvanicus, the fall field cricket or common black field cricket. Here's a page about field crickets, followed by one about fall field crickets that includes recordings of their songs...

I keep these crickets as pets year-round myself so can attest to their good pet qualities. They like to be kept on dry sand or soil and have something to hide in or crawl under, even if it's just a couple of small flat rocks laid overtop of eachother or a little pile of grass. They also like a warm light for sunbathing (careful you don't cook him, especially if he's in a container made of glass!) and love to eat a bit of cat or dog kibble or tropical fish flakes/pellets in addition to all kinds of vegetables, fruits and plain bakery products (mine got chunks of cornmeal muffins yesterday...NO butter, please). A bottle cap or pill bottle top will do as a watering dish--crickets do best when they have access to water all the time. If you're gentle and careful with your handling, most of these crickets can get tame enough to climb from hand to hand without trying to jump off, and some will even learn that your palm is a nice warm place to sit and groom and eat a treat. Never let them fall very far when you handle them, though--work over a sofa or chair or near the floor. Large crickets are more fragile than grasshoppers, and their abdomens may even burst if they fall any distance onto a hard surface.
