    • n katydid An orthopterousinsect of the family Locustidœ of large size, green color, and arboreal habits. Its note (which is imitated by its name) is produced by stridulation. The common katydid is Cyrtophyllum or Platyphyllum concavum. It is abundant in the central and eastern United States, where its shrilling call is one of the most familiar sounds of a summer night. The wing-covers are long, entirely covering the hind wings, and of a pretty pale-green color. By means of the long similar-shaped ovipositor, the eggs are pushed into crevices in the soft bark and stems of plants. The round-winged katydids are several species of Amblycorypha, as A. rotundifolia, abundant in the northern United States and Canada. Microcentrum retinervis is the angular-winged katydid. Another katydid, of slender form, is Phaneroptera curvicauda.

Above the streams that, wandering, win
To where the wood pool bids,
Those haunters of the dusk begin,—

Like them skreeks we hear in nightmare dreams.

The bee dreams in the cherry bloom
That sways above the berry bloom;

In leafy deeps of dreary gloom:
The forming dew is globing on the grasses,
Like rich spilled gems of some dark queen that passes.
"Falerina" by Madison Julius Cawein
When the katydid sings and the cricket cries,
And ghosts of the mists ascend;
And the evening star is a lamp i' the skies,
And summer is near its end—
It's oh, for the fence and the leafy lane,
And the twilight peace and the tryst again!
"In The Lane" by Madison Julius Cawein
