Butterfly Color Patterns Reveal Clues About the Genes That Build Insect Wings

By Viviane Callier Butterfly wings are natural canvases decorated with elaborate color patterns, but how these patterns develop and evolve is still incompletely understood. Now, a new study in Scientific Reports has identified the genetic code by which butterflies can assign color patterns to different parts of their wings during development. The code is based […]

Adult Bed Bugs Prefer Red and Black, But Avoid Yellow and Green

By Josh Lancette Researchers from the University of Florida and Union College in Lincoln, NE wondered whether bed bugs preferred certain colors for their hiding places, so they did some testing in the lab. The tests consisted of using small tent-like harborages that were made from colored cardstock and placed in Petri dishes. A bed […]

The Eyes of Common Bluebottle Butterflies Have 15 Photoreceptor Classes

When researchers studied the eyes of common bluebottle butterflies (Graphium sarpedon), they found at least 15 different classes of “photoreceptors” — light-detecting cells comparable to the rods and cones in the human eye. Previously, no insect was known to have more than nine. The results of their study are published in the journal Frontiers in […]
