chirr

A pensive stillness passed while they listened to the hushed chirr of insects in the trees that surrounded the cemetery like an embrace.

From "The Serpent King" by Jeff Zentner

But on leading up his horse within ten or twelve feet of the pin, it gives a little "chirr" and dives down out of sight.

From Wild Animals at Home by Ernest Thompson Seton

I heard the death-moth tick and stir, Slow-honeycombing through the bark; I heard the cricket's drowsy chirr, And one lone beetle burr the dark— The sleeping woodland seemed to purr.

From Poems by Madison Julius Cawein

Hung with the crimson aigrets of its seeds The purple monkshood bleeds; The dewy crickets chirr, And everywhere are lights of lavender; And scents of musk and myrrh To guide the foot of her.

From The Cup of Comus Fact and Fancy by Madison Julius Cawein

The air was full of a faint far chirr of night insects, like an elfin serenade, and here and there among the trees pulsed the greenish-yellow spark of a firefly.
