Ericodesma aerodana is a species of moth of the family Tortricidae. It is endemic to New Zealand and is found in the North and South Islands. The species inhabits sand dunes and larvae feed on Pimelea prostrata. Adults are on the wing from October to January and are active at twilight. This species is classified as "At Risk, Declining" by the Department of [Conservation (New Zealand)|Department of Conservation] as its larval host plant is under threat from habitat loss and the invasive to New Zealand plant, sea spurge.
