Psinidia fenestralis Atlantic-coast locust

Key Characteristics

The Atlantic-coast locust is a medium-sized speckled grasshopper with slightly flattened antennae and a head that is strongly elevated above the pronutum (dorsal plate behind the head). A short, dull yellow stripe runs from the eye to the edge of the pronutum, which has a prominent central longitudinal ridge (median carina) that is deeply cut by two narrow grooves (sulci).

CountyNumber of OccurrencesYear Last Observed

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.


The Atlantic-coast locust inhabits grassy dunes, sand barrens, and sandy blowout areas adjacent to forest edges.

Natural Community Types

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

It is likely sensitive to alteration of dune habitat, especially for mining, development or other activities. Prohibit ORV use in sensitive dune areas.

Active Period

Active from fourth week of August to second week of September

Survey Methods

This species can be found by conducting visual surveys or sweep-netting in appropriate habitat.
