I photographed this larval T. virginica last week – the larvae are distinctive owing to their large size (about 1.5 to 2 times the typical Cicindela sp larva) and a pale white band about the pronotum.

While the larvae are very shy and hard to approach during the day, at night the larvae are quite tolerant and, with care, are easy to photograph. I have also found that Tetracha larvae are the easiest to “fish” from their burrows as they will readily seize the blade of grass and will hold on fiercely.
