A highlight was watching a pair of grasshopper who patiently ignored us for 10 minutes while they went about their business. It appears that November was mating season. I was curious about their species but didn't have the heart to interrupt them to check their wing pattern. They finally jumped away, flying awkwardly to a more private rendezvous.

A recent study reported by Time demonstrated that some grasshoppers have learned to adapt to human noise. They demonstrated that "male bow-winged grasshoppers, Chorthippus biguttulus, who live near highways adapt their mating calls to make them audible to females over expressway noise." They placed 188 separate grasshoppers in a box facing a female and recoredd their calls. Those collected by highways produced a higher-pitched call to rise above highway noise. This study was done in Germany and it hasn't been repeated yet along I-44.
