Well-known in Lepidoptera and Coleoptera, the distinct black-orange-black color pattern has never been fully documented in Hymenoptera—until now. A study of more than 1 million wasp, bee, and other hymenopteran specimens finds a wide range of variations of the pattern present in 23 families within the order Hymenoptera.
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.
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.
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.
