Wing pattern varies greatly, but most individuals are marked with an incomplete median fascia and conspicuous costal spot. The distal half of the wing may be lightly shaded or solid brown. Labial palpi are long. Males lack a forewing costal fold. Adults may be confused with other Sparganothis. Sparganothis tunicana is similar but can be distinguished from S. senecionana by its smaller size and shorter labial palpi. Biology Sparganothis senecionana completes a single annual generation over much of its range. Adults are present April to August depending on location. Larvae are highly polyphagous and generally feed on flowers of the host. 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. Host plants Larvae of S. senecionana have been recorded feeding on plants in nearly 20 families.
