The antennae are pectinate (comb-like), and the compound eyes are very large, being contiguous in the male and almost united in the female.

The larvae are whitish grubs with light tan heads; their urogomphi (spines on the last segment) are not recurved but are relatively straight.

[1][2] Dendroides canadensis is found in eastern North America, its range extending from Manitoba and Nova Scotia in Canada to Oklahoma and Florida in the United States.

[4][5][6] In response to decreasing temperatures in the fall, D. canadensis larvae cease eating and drinking, and they evacuate the gut.

In order to avoid mortality, other body fluids also need to remain liquid, and D. canadensis increases the antifreeze proteins in its hind-gut and primary urine at this time.
