Paroxya hoosieri Hoosier locust

Key Characteristics

The Hoosier locust is a yellowish green to olive-brown grasshopper with a prosternal spine (conical projection between the front legs on the lower body surface). The tegmina (leathery front wings) are two-thirds the length of the abdomen.

Information is summarized from MNFI's database of rare species and community occurrences. Data may not reflect true distribution since much of the state has not been thoroughly surveyed.

Habitat

It inhabits lush, moist, wet areas with sedges, rushes, and grasses around the margins of ponds, small lakes, bogs, marshes, and swales. It is thought that females oviposit in decayed wood. An herbivore, this species feeds on cattails, water-plantain, and joe-pye-weed.

For each species, lists of natural communities were derived from review of the nearly 6,500 element occurrences in the MNFI database, in addition to herbarium label data for some taxa. In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.

Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.

Management Recommendations

Maintain and restore suitable moist, open, grassy wetlands. Avoid dredging, filling, or other hydrologic alterations. Prescribed fire may be an appropriate habitat management tool but care should be taken to not burn all occupied habitat at once. Remove invasive plants that could alter habitat quality such as giant reed (Phragmites australis), narrow-leaved cattail (Typha angustifolia), or glossy buckthorn (Rhamnus frangula). Prohibit ORV use in occupied or sensitive areas.

Active Period

Active from fourth week of June to third week of October

Survey Methods

Conduct sweep net surveys in appropriate habitat.
