All Mediterranean species of the genus Hypselodoris have a pattern of yellow or white longitudinal bands over a dark blue background colour. Hypselodoris infucata is clearly different from all of these by the red pigmentation of rhinophores and branchial plume and by its colour pattern of yellow and blue spots over a cream or greenish background. Adults lay spiralled, whitish, ribbon-like egg masses. Each egg capsule encloses a single egg measuring near 90mm in diameter. The veliger larvae hatch after about 5 days at 25 C and they can be feeding in the plankton for up to about three weeks.
