 Now, adults and nymphs, they feed with these piercing, sucking, straw-like mouthparts that will suck out the xylem and phloem from our squash plants, which causes them to wilt. Squash frogs have one generation per year here in Utah, but there could be a potential partial second generation in southern Utah. They overwinter as adults and protect its sites along the buildings and underneath plant debris or compost piles.
