On the Picture-winged Leaf Moths (Lepidoptera: Thyrididae) from Chittagong University Campus, Bangladesh, with a report of a pouch-like structure on the caterpillar metathoracic legs of Aglaopus decussata Moore and notes on its life history

Abstract

We studied nine morpho-species belonging to six genera of thyridid moths from the Chittagong University campus, Bangladesh. Four of them are identified to species, of which three are new records for Bangladesh. Striglina Guenée, 1877 was the most diverse genus, with Striglina scitaria (Walker, 1862) observed more than ten times, while other species were observed only once. The life history and immature stages of Aglaopus decussata (Moore, 1883) are described for the first time. A modification on the caterpillar metathoracic legs is reported, which makes these legs resemble boxers’ hands with boxing gloves. Images of the adults of all the studied species, along with images of the female genitalia of Aglaopus decussata (Moore, 1883) and Collinsa cf. acutalis (Walker, [1866]), are provided. In addition, a taxonomic note on the misidentification of Picrostomastis subrosealis (Leech, 1889) from Bangladesh is provided.
