Sense Organs in Insects
Vision is the perception of light. Insects perceive light through three classes of sensory organs

Courtship-role-reversal in the bean weevil, Bruchidius dorsalis (Coleoptera: Bruchidae): Interplay between male-male competition and cryptic female choice
This study examined the pre- and post-copulatory advantage of greater investing males

The rise of the ants: A phylogenetic and ecological explanation
In the past two decades, studies of anatomy, behavior, and, most recently, DNA sequences have clarified the phylogeny of the ants at the subfamily and generic levels.

Desert ants do not acquire and use a three-dimensional global vector
Desert ants (Cataglyphis fortis) are central place foragers that navigate by means of path integration.

Butterfly Speciation Event Recreated
In a matter of months, butterflies sporting the yellow and red wing color pattern of a wild species were created through simple laboratory crosses of two other wild species

How Butterflies Got Their Spots: A 'Supergene' Controls Wing Pattern Diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive--some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid.

Where Have All The Butterflies Gone?
Cold, wet conditions early in the year mean that 2006 is shaping up as the worst year for California's butterflies in almost four decades

Butterfly Migration Could Be Largest Known
Millions of painted lady butterflies that fluttered into California's Central Valley in the last week of March could be just the advance guard of one of the largest migrations of the species on record

K-state researchers study insects' immune system
How insects avoid getting diseases they can carry and spread to humans is the focus of research.

Invasive Ants Territorial When Neighbors Are Not Kin
A study shows that invasive Argentine ants appear to use genetic differences to distinguish friend from foe, a finding that helps to explain why these ants form enormous colonies in California.

Evolutionary Harmony For Stinkbugs And Their Gut Bacteria: A Perfect Match
With some 1 million species and counting, insects may be the most abundant class of animals living today.
