Taxonomy
Superfamily: Pyraloidea Family: CrambidaeSubfamily: PyraustinaeTribe: PyraustiniP3 Number: 801417.00 MONA Number: 4943.00
Comments: The genus Crocidophora contains seven described species from North America and India. There are three recognized species in North America and all occur in North Carolina.
Identification
Field Guide Descriptions: Covell (1984)Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Munroe (1976)                                                                                 
Adult Markings: The following is based in part on the description by Munroe (1976). In this species the forewing is light brown to light fawn-colored. The postmedial line is dark brown to blackish, is conspicuously toothed, and is evenly curved between the inner margin and costa. It is followed by a similar toothed subterminal line with deep acute dentations that point inwardly on the veins. The area basal to the postmedian line has a few dark smudges and irregular marks that may is part represent remnants of a broken antemedial line. The terminal line is represented as a series of small but distinct black dots, and the costa is darker the the general ground color. The males have a large fovea in and behind the cell of the forewing with an overlapping ridge of shining scales on the underside (Munroe, 1976).

Crocidophora pustuliferalis is similar to Ostrinia penitalis, but the latter has a well-developed antemedial line and lacks a line of black dots on the termen. The males also lack a fovea.
Adult Structural Features: Munroe (1976) has descriptions of the male and female genitalia. The males have a large fovea in and behind the cell of the forewing with an overlapping ridge of shining scales on the underside (Munroe, 1976).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larvae feed on native canes (Arundinaria), but very little has been reported on the larval life history. Jim Petranka and Becky Elkin observed larvae and one late-instar or prepupa that had constructed a cocoon in several frass-ladened nests in Madison County. The nests consisted of silk-bound young leaves and shoots of Giant Cane and contained large amounts of light brown frass pellets. There were 1-3 larvae per nest. Shelters with a single larva were simpler than communal nests, with the shelters having only 2-3 leaves that were bound together. One pupating larva was near the bottom of a nest where it constructed a cocoon that consisted of a thin layer of silk that was covered with frass. An adult emerged on July 12, 2023.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
Distribution in North Carolina
Distribution: Crocidophora pustuliferalis is found in the southeastern U.S. from Maryland and North Carolina westward to Kentucky, Arkansas, and northeastern Oklahoma, and southward to central Florida, Alabama, southern Mississippi and Louisiana. As of 2023, we have records from all three physiographic provinces but are lacking records from the southern Coastal Plain where the host plant is common.

Flight Comments: The adults mostly fly from March through September in different areas of the range, but are occasionally seen during the winter months. As of 2023, we have records from late-March through mid-August. Local populations appear to be bivoltine in North Carolina.
Habitats and Life History
Habitats: Local populations are centered around canebrakes and cane thickets.
Larval Host Plants: The larvae feed on native cane (Arundinaria spp.; Munroe, 1976). In North Carolina, this species has been found in Coastal Plain habitat where Switch Cane (Arundinaria tecta) is the most likely host, as well as in the Blue Ridge where River Cane or Giant Cane (A. gigantea) is the most likely host. None of our occurrences are associated with Hill Cane (A. appalachiana). One record from a residential neighborhood in Orange County was from a site next to a large stand of cultivated Black Bamboo; no native cane is located within several miles of the site. - View
Observation Methods: The adults are attracted to lights and the larvae can be found in webbed leaves of cane.

Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: GNR S3S4
State Protection: Has no legal protection, although permits are required to collect it on state parks and other public lands.
Comments: This species in generally uncommon in the state due to its reliance of cane.

Comment: A prepupa is a thin silk cocoon; the outside frass was removed to reveal the thin, silk covering around the larva.
