The Sand Dart (Agrotis ripae) is a species of moth in the Noctuidae family.
This medium-sized moth is sandy-brown with various markings, which do range. The oval and kidney mark are sometimes broken, and there is a dagger mark. Some forms are almost white, though darker forms are very rare. This species flies during June and July, and is usually earlier than the similar Coast Dart.
The larvea feed on various plants including Sea-purslane and Common Orache. The larvae can be seen from August till the next Spring.
This species is classed as Nationally Scarce B in Britain, and is found in sand-dunes scattered around the British coast, including Ireland.
