FWL: 8.0-11.0 mm
Forewings are light brownish gray with brown or gray fasciate markings. Males have a forewing costal fold. Male genitalia are characterized by valvae that appear to be twisted dorsally. Female genitalia are characterized by a twisted ductus bursae and a single daggerlike signum in the corpus bursae.
Adults may appear similar to other gray-brown archipines with a fasciate forewing pattern. A genitalic dissection can be used to confirm identity.
Late instar larvae are pale cream with a reddish-brown line running along the SD setae and faint reddish-brown markings on each segment dorsal to the pale D setal pinacula. The head and thoracic legs are dark brown. The prothoracic shield is dark brown posteriorly, becoming pale cream anteriorly.
Isotenes miserana completes several generations per year. Generations are overlapping and adults may be present year-round in some locations.
Females lay eggs in masses and surround them with "fences" constructed from specialized scales on the abdomen. Larvae tunnel into fruit and feed just below the skin; they may also feed on buds and young leaves. Pupation occurs in the larval feeding shelter.
Larvae of I. miserana are polyphagous and have been recorded feeding on citrus, camellia, macadamia, peach, rose, and a variety of other plants in at least 14 families.
