Not long ago, I got an email from grasshopper expert David J. Ferguson confirming my identification of Pardalophora phoenicoptera (and also encouraging my recent fascination with band-winged grasshoppers (family Acrididae, subfamily Oedepodinae) and their marvelously cryptic nymphs). He suggested that I might also find the “toad lubbers” (family Romaleidae) and pygmy grasshoppers (family Tetrigidae) interesting, since they too have many of those qualities I was finding attractive in band-winged nymphs, only on a very small scale. It was a prescient comment, as I’d already started taking notice of the pygmies and even photographed one before ever getting his email.
I take this individual to represent Tettigidea lateralis (black-sided pygmy grasshopper), which I saw at Shaw Nature Reserve during my May search for Cylindera unipunctata. Actually, I’m not sure I would have even noticed this individual, as I walked along the trail going from open woodland through dry dolomite glade, had it not actually been sitting on my net rim. I haven’t studied pygmies all that much, other than to note that they seem common around streams and other wet areas and are usually quite small. This one, however, at close to 15mm in length seemed positively gigantic! I placed it on the barren dolomite along the trail, expecting it to flee immediately. Instead it just sat there—begging me to photograph it, so I did.
This one appears to be a female with a short pronotum, but I can’t tell if it is an adult with short wings or still a nymph (it was certainly large enough to be an adult!). Either way, I’m interested in the function of the bright white femoral marking on what is otherwise a very cryptically colored individual.
