Key Characteristics

Angular spittlebugs are small (males 4.0 - 4.4 mm, females 5.0 - 6.1 mm) compared to L. gibbosa with a weakly inflated sucking pump and a humpback. Their chocolate coloration and blackish brown V-shaped markings on the forewings may also be seen upon close examination.

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.


This species feeds on a wide variety of plants but is closely associated with prairie fens and in particular it host plant, spike-rush (Eleocharis sp.).

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

Prescribed burns may help set back shrub encroachment but intense burns over an entire site may be detrimental to the population through direct losses or indirectly by loss of host plants. The fire should be light to moderate and conducted on a rotational basis to ensure some habitat is always present. Generally, insecticides and herbicides should not be applied, however, selective treatment of woody 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 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 in an area because they occur in small colonies within a limited portion of available habitat. Some adult spittlebugs have even been detected in spider webs so check these as well.
