Introduction
The subfamily Dioptinae comprises of 456 known species arranged into 2 tribes and 43 genera. The moths are almost entirely neotropical in distribution: only one species Phryganidia californica being found north of Mexico. All are day-flying, and most are brightly coloured, typically with aposematic patterns in yellow, orange or white on a black ground colour. They are involved in Batesian mimicry rings with various Ithomiine butterflies, and with moths from the subfamilies Arctiinae ( Erebidae ) and Sterrhinae ( Geometridae ).
Dioptinae, like most other moths have tympanal organs 'ears' at the base of the thorax. These are generally accepted as having evolved to allow them to detect the echo-location calls of predatory bats. These moths however are all day-flying species, and experiments have shown that they are virtually deaf. This implies that their ancestors were nocturnal, and that the ability to hear was lost when they evolved to become day-flying and were no longer exposed to bats.
All 25 Lyces species have a black or dark brown ground colour, with longitudinal streaks or diagonal bands in yellow or orange. They are similar in appearance to moths in the family Arctiinae, and can sometimes only be distinguished from them by close examination of the forewing venation which is trifine in Dioptinae and quadrifine in Arctiinae.
Lyces annulata is found in Colombia, Venezuela, Ecuador, Brazil, Peru and Bolivia.
