view caption

Taxonomy

Superfamily:
Noctuoidea

Family:
Erebidae

Subfamily:
Arctiinae

Tribe:
Lithosiini

P3 Number:
930218

MONA Number:
8045.00

Comments: One of eleven named species in this genus that occur in North America north of Mexico (Lafontaine and Schmidt, 2010, 2015), of which six been recorded in North Carolina (several others are still undescribed)

Identification

Field Guide Descriptions: Covell (1984)

Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD

Technical Description, Adults: Forbes (1960)

Adult Markings: Strongly sexually dimorphic. Males are small, pale grayish-brown moths that closely resemble the pale members of the Crambidia pallida complex; they are easily distinguished, however, by their pectinate antennae. Females have dark gray wings, bordered by yellow along the costal margin and with varying amounts on their thorax. They resemble Eilema bicolor in terms of coloration but are smaller and have very distinctive antennae (see below).

Adult Structural Features: Males have pectinate antennae, whereas all other species of Crambidian in our area have simple antennae. Females are also unique in their possession of roughly serrate antennae.

Structural photos

Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].

Immatures and Development: Descriptions of the larvae are apparently unavailable.

Distribution in North Carolina

Distribution: Most of our records come from the Coastal Plain and its occurrence in the Piedmont and Mountains needs to be better understood.

County Map: Clicking on a county returns the records for the species in that county.


Flight Dates: High Mountains (HM) ≥ 4,000 ft. Low Mountains (LM) < 4,000 ft. Piedmont (Pd) Coastal Plain (CP) Click on graph to enlarge
Flight Comments: Appears to be continuously present from spring to fall but with two peaks in abundance

Habitats and Life History

Habitats: The vast majority of our many records for this species come from Longleaf Pine habitats, including savannas, flatwoods, and sandhills -- if this species feeds on tree lichens, then those growing on Longleaf Pine are likely suspects. Lithosiodes has also been recorded at a few non-Longleaf habitats, including sites in Pond Pine Woodlands, floodplain ridges in the lower Roanoke River floodplain, and at a few sites in the Great Smoky Mountains National Park. Pines would still be the common denominators, but would include Pond Pine and Loblolly in addition to Longleaf.

Larval Host Plants: Like most Lithosiines, probably feeds on lichens, bark algae, and Cyanobacteria (Covell, 1984; Wagner, 2005). - View

Observation Methods: Comes regularly and occasionally abundantly to blacklights but has rarely been recorded at bait

Status in North Carolina

Natural Heritage Program Status:

Natural Heritage Program Ranks: G5 SNR [S4S5]

State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands

Comments: Although possibly a specialist on Longleaf Pine habitats, it also occurs to some extent in other habitat types and generally appears to be both widespread and secure in North Carolina
