Aucha velans explained

Aucha velans, the tide-watching mangrove moth,[1] is a moth of the family Noctuidae. The species was first described by Francis Walker in 1858.[2] It is found in Sri Lanka,[3] [4] Singapore and Philippines.[5]

The adult has a wingspan of 28–35 mm. They are found on the stems of Avicennia mangroves in a characteristic position where adults perch head down on tree trunks. Caterpillars are edge feeders of Avicennia species. Late instars reach the ground and pupate inter-tidally under rotting logs or in algal mats. They are major pests on mangroves and considered as severe defoliators.[6]
