How do Differential Grasshoppers deal with the cold nights of late autumn in Texas? Well, they find a spot on a branch or stem, and just ride the dark, chilly night out fully exposed.

The cold air makes the grasshoppers immobile and unresponsive, but they are not frozen. The temperatures did not drop below freezing on this night. Instead, they are in a state of torpor induced by the cool night air. Their body temperatures have dropped far below normal. Their exoskeletons are so chilled that the morning fog condenses on their bodies.

Things will be different for the grasshoppers in just a couple of hours. The warmth of the rising sun will reanimate them. By noon there will be hundreds of these insects hopping and jumping in every patch of tall grass.

I hope they’re enjoying the summer. Yesterday, as I strolling around downtown Fort Worth, I saw several of these. Or I’m pretty sure, now, that’s what they were. There’s was a point I would see one on almost every block: they were all yellow, ranging from bright and almost phosphorescent to orange-yellow. Just now I noticed one on the window outside my little office. I took my iPad out there and took a quick video just so I’d remember it.
I recently moved to Hurst TX
