Squash Lady Beetle or Squash Ladybug

Natural Habitat

Agricultural fields, gardens, and areas where cucurbit plants (squash, pumpkins, gourds, cucumbers, melons) are grown.

Diet & Feeding

Unlike most lady beetles which are predatory, the Squash Lady Beetle is herbivorous. Both adults and larvae feed on the leaves, stems, and fruits of cucurbit plants, using their chewing mouthparts to scrape off the plant surface.

Behavior Patterns

Adults and larvae can be found feeding on cucurbit plants. They undergo complete metamorphosis, with eggs laid on the undersides of leaves, followed by spiny, yellowish larvae, pupae, and finally adults. They can overwinter as adults in protected locations.

Risks & Benefits

This insect is considered a pest in agriculture and gardening because its feeding can cause significant damage to cucurbit crops, leading to reduced yields and plant health. There are no known benefits to humans or the ecosystem, and it poses no direct risks to human health.
