Most moths feed on flower nectar and thus behave as pollinators. Another part lives for a few hours or days and accumulates fat in the larval stage, so adults barely eat, drinking water instead.
However, several groups of the Erebidae family (ex-Noctuidae latu sensu + Arctiidae) are frugivores, feeding on decomposing ripe fruits. They include the well-known and popular underwings (genus Catocala) from the northern temperate region, which can be attracted by brushing fruit puree over bark and tree trunks.
Some genera of the subfamily Calpinae have specialized in piercing the intact peal of fruit with the proboscis, the mouthpiece typical of 99% of adult Lepidoptera, which in this case has a pointed and barbed tip, allowing the moth to pierce the rind of the fruit to sip its juice and some of them are considered citrus orchard pests.
In our region occurs the colorful genus Eudocima of Pantropical distribution (with species in all tropical regions) exemplified by the individual pictured here on a fallen fruit.
Finally – as a curiosity; – Nature went a little further on with some improvements over the proboscis modifications involved in piercing intact fruits allowing for the appearance of some blood feeding (hamatophagous) species in Southeast Asia capable of piercing mammal skin to feed on their blood, especially that of large animals including local cattle. These are the vampire moths of the genus Calyptra.
The typical feeding habit in this Asian genus is to drink on the lacrimal secretions of these animals, but less than half a dozen species specialized in hematophagy just like mosquitoes.
