Unexpected benefits from food competitors

When laying their eggs, female hawkmoths rather share a host plant with competitors in order to escape from parasitic wasps. more

Gut enzyme in cockchafer larvae activates dandelion defense mechanism

Removing the sugar component from a toxin in dandelion roots increases larval growth while simultaneously deterring the larvae from feeding. more

Learning helps tobacco hawkmoths to select a nectar source and oviposition site more efficiently

Learned odors influence the moths' preferences for certain flowers and host plants. Olfactory sensory cells on the proboscis, on the other hand, play no role in learning. more
