Diet & Feeding

Omnivorous; feeds on decaying organic matter, plant materials, and sometimes can be a minor pest to greenhouse plants.

Behavior Patterns

Nocurnal insects that are burrowing in nature; this species is notable because populations in many areas are parthenogenetic, meaning females reproduce without males.

Risks & Benefits
