In honor of Valentine's Day, here's a look at recent entomological research on how some insects and other arthropods woo one another with gifts.
Researchers find that the butterfly species Bicyclus anynana passes down a preference for leaves that smell like banana to its next generation—another curious example of inheritance of a learned trait.
An entomologist examining wasp specimens in fossilized amber from the Eocene (34–55 million years ago) has identified them as a new species, Brachyelatus marthae, and the first fossil specimens from the chalcid wasp subfamily Chrysolampinae.
Research at Penn State University reveals the intricate flips and twists that a fly performs to execute an inverted landing. Understanding the mechanics of the motion could help engineers design robotic fliers that land upside down, too.
