noun
katydid
KAY-tee-did/ˈkeɪtidɪd/
A usually green insect related to crickets, with long antennae.
A green katydid rests on a leaf near the window.

Etymology
The name imitates the harsh call made by the male as it vibrates its wings. It identifies the insect through its conspicuous nighttime sound rather than through descriptive word roots.
In context
As darkness settles over forests and grasslands, the katydid's world comes alive.
More examples
- We hear katydids calling from the trees after sunset.
- The katydid's long antennae extend beyond the edge of the leaf.
- I almost miss the katydid among the green leaves.
