The eggs are a reddish brown and will hatch in about 7 to 10 days. Once hatched, the tiny borer enters the stem and feeds on the insides of the stem. When the vines of the plant become woody and less succulent, the borer will attack the fruit. The borer will reach maturity in about 40 days, and in August and September will enter the soil and form their cocoons. Symptoms of borer infestation include sudden wilting of a runner or the entire plant, hollow vines filled with shiny frass, and yellow pellets of frass on the soil surface near the plant base.
