Overview
The Figeater Scarab (Cotinis mutabilis) is a large, metallic green beetle commonly found in the southwestern United States. Closely related to June beetles, this species is best known for its attraction to ripe and overripe fruit. While the larvae play a beneficial role in breaking down organic material in soil, adult beetles are often considered pests due to their feeding habits and tendency to congregate in fruit-bearing trees.
Figeater scarabs are particularly active during the warmer months, when fruit begins to ripen. Their loud buzzing flight and tendency to crash into objects make them highly noticeable in gardens and orchards. Although not dangerous to humans, their feeding can reduce fruit quality and attract secondary pests such as flies and wasps.
Identification
- Large beetle, typically 1–1.25 inches long
- Metallic green coloration with velvety texture
- Loud, clumsy flight
- Larvae (“crawly backs”) move on their backs in soil
Habitat
Figeater scarabs are commonly found in gardens, orchards, compost piles, and lawns rich in organic matter. Larvae develop in soil containing decaying plant material, manure, or compost.
Behavior and Damage
Adult beetles feed on soft fruits such as figs, peaches, and grapes. Their feeding often results in fruit damage, rot, and increased attraction of other pests. Larvae, however, primarily feed on decomposing organic matter and contribute to soil health.
Prevention and Control
Removing overripe fruit, managing compost, and reducing excess organic matter in soil can help limit populations. Netting fruit trees and harvesting promptly are effective preventive measures.
