New research by the University of Washington and the UA shows that background odors can interfere with pollinators’ ability to find flowers.
Car and truck exhaust fumes that foul the air for humans also cause problems for pollinators. (more…)
GAINESVILLE, Fla. — University of Florida lepidopterist Andrei Sourakov has spent his life’s work studying moths and butterflies. But it was his teenage daughter, Alexandra, who led research on how color impacts butterflies’ feeding patterns.
The research shows different species exhibit unique foraging behaviors, and the study may be used to build more effective, species-specific synthetic lures for understanding pollinators, insects on which humans depend for sustaining many crops.
In a study appearing online in April in the journal Psyche, researchers used multi-colored landing pads and baits in the Florida Museum of Natural History’s McGuire Center for Lepidoptera and Biodiversity on the UF campus to determine that some butterflies use both sight and smell to locate food, while others rely primarily on smell.

Predators select their prey in order to eat a nutritionally balanced diet and give themselves the best chance of producing healthy offspring.
A University of Exeter and Oxford-led study published in Proceedings of the Royal Society B shows for the first time that predatory animals choose their food on the basis of its nutritional value, rather than just overall calorie content.
An international team of scientists from the Universities of Exeter and Oxford in the UK, University of Sydney (Australia), Aarhus University (Denmark) and Massey University (New Zealand) based their research on the ground beetle, Anchomenus dorsalis, a well-known garden insect that feasts on slugs, aphids, moths, beetle larvae and ants.
