The wingspan is 25-30 mm. In Australia there are about 1-2 generations per year. 〔Mansfield S, Kriticos DJ, Potter KJB, Watson MC (2005) Parasitism of gum leaf skeletoniser ( Uraba lugens) in New Zealand.

==General==
''Uraba lugens'' is nicknamed the "Mad Hatterpillar" because of its distinctive exoskeletal feature. Every time it sheds the head portion of its exoskeleton, the exoskeleton stays attached to its body. Over time, developing through its life span, the head grows bigger and sheds increasingly larger exoskeleton shells, which build upon each other.〔>〕
''Uraba lugens'' develops as a typical moth. The life cycles occur twice a year: once in the summer and once in the winter. Eggs are laid in groups of 100-200 and are about 1 mm in diameter .〔>〕 Caterpillars are mostly yellow with some black markings. After hatching from a cocoon, the resulting moths are grey in color. During the larvae stage, ''uraba lugens'' can cause damage to trees by chewing. Pesticides are suggested for keeping populations in check and minimizing damage.
