Taxonomy
Superfamily: Pyraloidea Family: CrambidaeSubfamily: CrambinaeTribe: CrambiniP3 Number: 800868.00 MONA Number: 5433.00
Species Status: "I have some confusion with this, but it generally seems distinct from F. profanellus" (Scholtens, 2017)
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: Head and thorax are pale ochraceous yellow; the palps are fuscous on the outside (Fernald, 1896). The forewings are also pale ochraceous with a white stripe running from the base to the cell, following which there are a series of white lines on the veins. The costa is usually fuscous, with the area between the costa and the white longitudinal streak being quite dark in some specimens. The median line is represented by two or three dark spots that form a nearly straight line from the cell to the basal third of the inner margin. The subterminal line is brown and edged outwardly with silver. It forms a curve below the costa and has a tooth on the fold. A terminal line is composed of black dots and the fringe is gray. Hindwings are pale fuscous.

Fissicrambus haytiellus and F. profanellus are two very similar forms that often cannot be reliably identified based on external morphology. Both the males and females of these species can be reliably identified using genitalia and specimens that have been examined to date from North Carolina have all proven to be F. profanellus (J. B. Sullivan, personal communication). As such, we are treating all specimens that resemble haytiellus/ profanellus as F. profanellus. Records for F. haytiellus in North Carolina that are on internet resources (e.g., MPG) have not been verified by genitalia and additional work is needed to document this species within the state.
Wingspan: 10-20 mm (Fernald, 1896)
Adult ID Requirements: Identifiable from photos showing hindwings, abdomen, or other specialized views [e.g., frons, palps, antennae, undersides].
