Explanation of Names
Species name from Greek camelo
camel, plus Latin folius
(?) a leaf (1)
, referring to the shape of the wings, presumably--held over the back to form a camel-like hump(?).
Forewings form cup over abdomen, many conspicuous veins. Pronotum has two shallow grooves. Both sexes stridulate "katy-did, katy-didn't" at dusk into night. Song varies geographically.
Deciduous forests--often heard, but seldom seen, since mostly lives in forest canopy.
Midsummer to frost. July-October (Michigan), July-September, or November (North Carolina)
Foliage of deciduous trees, and shrubs(?)
Eggs are inserted into loose bark or young stems of trees and hatch in spring. One brood per year. Both sexes stridulate, males more loudly. Song varies geographically. Flightless, but may glide to lower branches of trees (2)
. Sometimes seen perched on shrubs. Does not come to lights frequently (pers. obs., P. Coin).
One of the few North American insects, perhaps, memorialized in verse. Below is an excerpt from Oliver Wendell Holmes, Sr.

(1831), full text available from Project Gutenberg
I LOVE to hear thine earnest voice,
Wherever thou art hid,
Thou testy little dogmatist,
Thou pretty Katydid
