Summary

Allonemobius fasciatus, commonly known as the striped ground cricket, is a widely distributed species in North America characterized by its ability to hybridize with A. socius. It prefers grassland habitats and shows unique adaptations in mating behavior based on environmental factors.

Physical Characteristics

Morphology and song are identical to A. socius; typically shorter wings with wing size determined by daylight hours during development.

Identification Tips

Distinguished from A. socius primarily by range or through allozyme assay.

Habitat

Prefers short grassland habitats, and can be found in open grassy areas.

Distribution

Widely distributed in North America, covering both eastern and western portions. Inhabits northern regions, residing in areas where A. socius is found in lower elevations.

Diet

Omnivorous, feeding on a variety of organic materials.

Life Cycle

A. fasciatus is a univoltine species; nymphs take up to two months to hatch and development is photosensitive.

Reproduction

Produces one brood per season; females use an ovipositor to deposit eggs into the ground, often using a reproductive strategy called bet hedging.

Ecosystem Role

Acts as both predator and prey within its ecosystem, contributing to the food chain.

Evolution

Studied in evolutionary biology for its ability to hybridize with A. socius, demonstrating genetic similarities restricted to X chromosomes only.
