The nymph of the plains clubtail is a large in size with a maximum length of 1 5/16 inches (33 mm). Its abdomen is thick for most of its length, then tapers to a rounded point at the end of segment ten. On each side of abdominal segments six through nine, there is a single, rear-facing spine. This species has no dorsal hooks.
Compared to dragonfly larvae, the nymphs show little variation in form. They tend to be slender and elongate, many having morphological adaptations for holding their position in fast flowing water. They are more sensitive than dragonfly nymphs to oxygen levels and suspended fine particulate matter, and do not bury themselves in the mud. [25]

The order was formerly named Protodonata, the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata (damselflies and dragonflies). They range in Palaeozoic (Late Carboniferous ...
