The lipocalins that have been identified as biliproteins have been found in a wide variety of insects, but mainly in the order Lepidoptera. Scientists have discovered them in the large white butterfly and a number of moth and silkmoth species, including the ailanthus and domestic silkmoths, giant silkworm moth, tobacco hawk moth, honeycomb moth, and the puss moth.[1][8] The biliproteins associated with these insect species are the bilin-binding proteins, biliverdin-binding proteins, bombyrin, lipocalins 1 and 4, insecticyanin, gallerin and CV-bilin respectively.[6][3] The biliproteins found in the tobacco hawk moth and pussmoth make up a major part of the insects’ haemolymph fluids.
