Plants and Animals
Papaipema beeriana Blazing star borer
Key Characteristics
This moth has a wing-span of 1.2-1.5 inches (3.1-3.6 cm). It has two color forms, both spotted and unspotted. The unspotted form has forewings which are dull brownish, frosted with whitish scale-bases, and with scattered white scales; markings practically absent or very faint. The hind wings are a paler and more uniform gray. The spotted form, lacinariae Bird, has forewings similar to the unspotted form with the exception of white spots.

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 blazing star borer occurs with its larval host plant, blazing star or snakeroot (Liatris spp.) The species has been recorded from a variety of plant communities crossing gradients from wet to dry including lakeplain prairies, prairie fens, and sand prairie or barrens. At known sites associated prairie plants typically include big bluestem (Andropogon gerardii), Indian grass (Sorghastrum nutans), common mountain mint (Pycanthemum virginianum), tall coreopsis (Coreopsis tripteris), Ohio goldenrod (Solidago ohioensis), Culver's root (Veronicastrum virginicum), and switch grass (Panicum virgatum).
Natural Community Types
- Dry sand prairie
- Lakeplain wet prairie
- Lakeplain wet-mesic prairie
- Mesic prairie
- Mesic sand prairie
- Oak-pine barrens
- Prairie fen
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
Almost all major workers on the genus have commented on the fire sensitivity of Papaipema eggs. Use of fire to control the pest species P. nebris. Land managers should always assume high mortality of Papaipema eggs in fall, winter, or spring burn units. To protect Papaipema populations retaining an adequate amount of the foodplant and to divide habitat into smaller burn units is recommended. No Papaipema site should ever be entirely burned in a single year. Foodplants spread over a large area or in several discrete patches reduce the risk from predators and parasitoids as compared to a comparable number of plants in a single dense patch. Most, if not all, of these parasitoids are native species and in most cases they do not need to be controlled. All known sites of beeriana on managed lands should be monitored periodically.
Active Period
Flight from fourth week of July to third week of October
Survey Methods
The best way to survey for this species is by blacklighting, a technique where a sheet is stretched across two trees or poles and an ultraviolet light is used to attract moths to the sheet. Moths can be collected directly from the sheet. Insects come to light usually in largest numbers on still, dark, cloudy nights when both temperature and humidity are high. You also can search for the larvae of many species of Papaipema by searching for signs of feeding activity in late July or early August. Reports of adults or lavae of this species must be documented with a voucher specimen or a good photograph and verification by a species expert.
