Shortly after the eggs hatch , the tiny squash borers will quickly tunnel into the stem of the plant . As they feast they grow larger , reaching their full size of it of about 1″ long in 2 - 4 weeks .
Once they are full - sized , they will leave the vine and set down into the soil , where they ’ll shape a cocoon and pupate . They winter in the land in 1″ long cherry-red - brown dyed cocoon , and will hole up until the next spring .
If you live in a cold clime like I do , there ’s only one genesis of squash woodborer per class . But in warmer climate , there can be two generations per twelvemonth .
