Pea weevil

The pea weevil (Bruchus pisorum L.). - This pest of field and garden peas winters as the adult beetle either in peas or in protected places and, after the pea pods begin to form, lays its eggs on them.

It is about one-fifth of an inch long, brownish, with black and white spots. The larvae bore their way into the peas, the holes they make either closing up or being too small to be noticed, and feed on the contents of the pea until full-grown.

They then pupate and, upon the production of the adult, those in the South leave the peas, while in the North they remain in them over winter.

Only one weevil usually feeds in a pea and the insect cannot reproduce in dried peas. There is therefore only one generation a year except where spring and fall crops of peas are grown.
