Another butenolide, siphonidin (102) and its glucoside, siphonoside, have been isolated from the leaves of Siphono-don australe (Celastraceae) (Wagner and Flitsch, 1981 Wagner et al., 1981). A new butenolide, isosiphonodin [3-hydroxymethyl-2(5H)-furanone] (103) and a small amount of siphonidin (102) were isolated from fifth-instar larvae of Yponomeuta cagnagellus. The larvae of this moth feed on the foliage of the spindle-tree, Euonymus europaeus (Celastraceae) (Fung et al., 1988).

Receptor cells sensitive to host plant compounds that stimulate feeding have also been identified in several species of Yponomeuta moths. Y. cagnagellus feeding on Euonymus has one dulcitol (sugar)-sensitive cell in the medial and one in the lateral sensillum styloconicum (van Drongelen, 1979,1980). Another species, Y. evonymellus, is also stimulated by dulcitol at the sensory and behavioral level even though the compound does not occur in its host plant. This contradictory result may be explained by the possible presence of dulcitol in an ancestral host plant (van Drongelen, 1979,1980).
