Larvae have been recorded feeding on Malvaceae plants.
Morphology Acontia species are characterized by an elongated palpi having pointed frontal tuft, and a well developed third segment. Antennae are simple and filiform, having no complex modifications or branches. Both the thorax and abdomen are covered in smooth scales, lacking tufts or patches. The forewing is bordered with non-crenulate cilia, and plain unnotched fringe along the edges. In terms of venation, veins 7 to 10 are stalked. The larval stage is characterized by the presence of four pairs of abdominal prolegs.
Distribution The species is found in parts of North Africa (Algeria, Egypt, Libya, Mauritania, Morocco, and Tunisia), the Arabian Peninsula (Saudi Arabia, Kuwait, and the United Arab Emirates), Middle East ( Iran, Iraq, Israel, Jordan, and Palestine) and Spain. In Egypt, it is distributed across Lower Egypt, Coastal Stripe, Gebel Elba and Sinai.
