Leaf-footed bug nymphs (likely squash bug nymphs)

They occur on cucurbit plants—squash, pumpkins, gourds, and related vines—especially on leaf undersides, stems, and fruit.

Nymphs and adults pierce plant tissues and suck sap using needle-like mouthparts, often causing yellowing, wilting, and fruit damage.

Nymphs commonly cluster and pass through several molts before becoming winged adults. Adults overwinter in plant debris and lay egg clusters on leaves during the growing season.

They are economically damaging garden pests but pose no significant danger to people. The image likely shows squash bug nymphs, though exact identification is limited by image resolution.
