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
Found throughout the lower peninsula in association with its host plant, nut-rush (Scleria sp.) and may occur in a wide variety of habitats that support nut-rush.
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
Mowing should be limited to early spring and late fall and only when needed. Prescribed burning may be conducted to control shrub invasion but should be done on a rotational basis. The fire intensity should be such that succession is set back but the host plant, nut-rush (Scleria sp.), is able to regenerate and thrive. Generally, insecticides and herbicides should not be applied, however, selective treatment of woody or non-native invasive vegetation (e.g. basal stem or stump application) may be an option to control these plants where prescribed burning is not feasible. The hydrology should be protected and incompatible land uses (e.g. conversion to agriculture, residential or commercial development, etc.) prohibited.
Active Period
Active from third week of April to third week of October
Survey Methods
The best way to survey for this species is to use a standard insect sweep net in suitable habitat. Several sweep samples may be needed to detect adults of this species.
Sweep net
Survey Period: From third week of July to fourth week of September
