The area I found this grasshopper was Canyon Country, California, USA In a desert/field area. I have been reading up on grasshoppers because I recently came into possession of a pink grasshopper (It was identified below as the common meadow hopper Chorthippus parallelus). One of the pages that I've read covers the eating of toxic plants by grasshoppers and how they change to bright colors to warn that they are toxic after eating poisons. Is this true? Could that explain the coloring of this grasshopper, or is it due to a recessive gene, or even erythrism? I'm trying to breed it, so any and all info on how to treat this little guy, history of the coloring if its genes, and the color changing toxic effect would be much appreciated. Here's a picture.
Chortippus parallelus is a common species in Europe that is according to my grasshopper id-guide extremely variable in color. It can be green, brown, yellow and even purple. I can verify that from field experience. Pink however is much more rare, and considered to be caused by Erythrism See https://en.m.wikipedia.org/wiki/Erythrism for explanation and several references to pink grasshoppers/katydids.
