Flexamia delongi Leafhopper

Key Characteristics

Males of this leafhopper species are quite small (3.4 - 4.1 mm) while females are only slightly larger (3.5 - 4.2 mm). The crown is usually 0.25 to 0.50 times greater than the interocular width. Male genitalia exhibit a space between the shaft and the gonopore extension of the apical process, when viewed horizontally.

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

The host plant for this species is little bluestem (Schizachyrium scoparium).

Specific Habitat Needs

needed in: Pine barrens.

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

Occupied sites should be protected from conversion to agricultural use or development and ORV traffic should be kept out. The hydrology should also be protected from alteration and non-native invasive plants and succession controlled. 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.

Active Period

Active from fourth week of June to fourth week of September

Survey Methods

The best way to survey for this leafhopper is to use a standard insect sweep net in suitable habitat. Several sweep samples scattered throughout suitable habitat may be needed to detect adults of this species.

Sweep net

Survey Period: From third week of July to fourth week of September
