Males lack a forewing costal fold. Sparganothis tunicana may be confused with other species of Sparganothis. Sparganothis senecionana is similar but can be distinguished from S. tunicana by its larger size and longer labial palpi. Biology Sparganothis tunicana completes a single annual generation over much of its range. Adults are present April to August depending on location. Life history information for S. tunicana is assumed to be similar to that of S. senecionana. In California, larvae hatch from the egg, construct a silk hibernaculum, and enter an obligate diapause that lasts through the dry season. Activity is resumed again at the onset of winter rains. Larvae feed on flowers. Host plants Larvae of S. tunicana are polyphagous have been recorded feeding on plants in more than 10 families.
