Squash vine borer is a moth species that is active during the day (diurnal). The larvae complete their growth and development on wild and domesticated species of the genus Cucurbita. Once only considered a nuisance to commercial growers, with the expansion of cucurbit production in the United States over the last decade, the squash vine borer has become a pest of economic importance.
