Different species of fruit flies exhibit remarkably different patterns of wing decoration. At the top is the familiar Drosophila melanogaster, the workhorse model organism of genetics, which differs markedly from other fruit fly species. Exploring a single gene that controls pigment deployment in fruit flies, a group led by UW-Madison biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed on the wing. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.

Staying in Asia for many years has given me the opportunity to get close to wildlife on many occasions. This female Smith’s green-eyed gecko chose to live on one of the chalets next to my home, taking advantage of the insects attracted by the lights at night.
