Diagnostic features

Adults

FWL: 6.5-9.5mm

Forewings are yellow with brown to purplish-brown markings. Most specimens are marked with a complete median fascia and the distal half of the wing is solid brown. Labial palpi are short in comparison to S. senecionana. Males lack a forewing costal fold.

Related or similar species

S. tunicana may be confused with other species of Sparganothis. Sparganothis senecionana is similar but can be distinguished from tunicana by its larger size and longer labial palpi.
