Harlequin Bug Coloration Influenced by Temperature During Nymphal Stages
A new study shows that harlequin bugs can adapt their pigmentation (or melanin levels) during their developmental stages based on outside temperatures. Such thermal melanism enhances the pest species' potential to invade new regions and environments.
What Gives This Butterfly Species the Only Blue Wings in its Subtribe?
Males of the butterfly species Mimeresia neavei feature blue, structurally colored wings, the only species in the Mimacraeina subtribe to do so. Researchers in Hungary credit M. neavei's blue wings to a form of coloration found in several butterfly groups but not experimentally examined within Lycaenidae.
How Butterflies Pattern Top and Bottom Wing Surfaces Differently
Researchers at the National University of Singapore have identified the gene transcription factors in butterflies that give rise to their different color patterns on the top and bottom sides of their wings.
