Why do crickets chirp?

The sound of crickets on a warm summer evening is just so soothing, isn’t it? All those little insects in the grass, talking to each other about… well, we don’t really know! In fact, we don’t know why they chirp at all. We asked neurobiologist Jon Lambert to tell us what’s actually going on out there at night. If you’ve got a question that just won’t let you rest, send it to us at BrainsOn.org/contact, and we’ll do our best to find the answer!
