Explanation of Names
cephalica is derived from Latin cephalicus meaning "relating to the head", perhaps a reference to the yellow head.
Size
forewing length 9-15 mm (Powell & Opler, 2009)(1)
Identification
Adults - forewing slender, white, held close to body when at rest; top of head yellow; antennae white, simple.
Range
Central Nevada, Utah and Wyoming south to Arizona, New Mexico, and west Texas (Powell & Opler, 2009).(1) Moth Photographers Group shows several records in and around Kentucky and Tennessee, and as far north as Alberta, Canada. BAMONA shows records records into Florida. Covell reports that specimens from West Virgina, North Carolina, and Kentucky may belong to this or an unnamed species.(2) BugGuide has one record for New Jersey (det. Chris Schmidt).
Season
Adults fly March through September. Multiple broods (Powell & Opler, 2009).(1)
Food
Larvae presumably feed on lichens and algae like other Lithosiini.
