Vampire Moth Discovered -- Evolution at Work
piggy submitted, created time 1 month 1 day (news.nationalgeographic.com)
A previously unknown population of vampire moths has been found in Siberia. And in a twist worthy of a Halloween horror movie, entomologists say the bloodsuckers may have evolved from a purely fruit-eating species.
Only slight variations in wing patterns distinguish the Russian population from a widely distributed moth species, Calyptra thalictri, found in central and southern Europe, known to feed only on fruit.
When the Russian moths were experimentally offered human hands this summer, the insects drilled their hook-and-barb-lined tongues under the skin and sucked blood. 
Researchers discover that growing up too fast may mean dying young in honey bees

Reactive oxygen species (ROS) occur as a by-product of aerobic metabolism and impair cellular function by damaging proteins, nucleotides and lipids. Organisms possess a variety of anti-oxidant mechanisms to mitigate the effects of ROS, and the oxidative stress model of aging and senescence suggests that physiological performance declines with age due to lifetime accrual of ROS-induced damage and progressively limited anti-oxidant capacity

It is so new, and so bizarre, that uber-naturalist E. O. Wilson has christened it "the ant from Mars." Martialis heureka, a native of the Brazilian Amazon, is the founding member of a new subfamily of ants. It adds a new branch to the ant family tree which split off from the others extremely early in the family's evolution. "It could represent a 'relict' species that retained some ancestral morphological characteristics," says discoverer Christian Rabeling, a graduate student in integrative biology at the University of Texas in Austin
Collective Motion and Cannibalism in Locust Migratory Bands

We know that plagues of mass migrating insects such as locusts are estimated to affect the livelihood of one in ten people on the planet. Because of above reason, identification of generalities in the mechanisms underlying these mass movements will enhance our understanding of animal migration and collective behavior while potentially contributing to pest-management efforts.

Finding your way home in the dark can be tricky. But migrating moths manage to cover huge distances at night by riding high-speed gusts of wind toward their breeding site. And they don't just catch some air and hope for the best, a new study suggests: Even when the wind strays off-course, the nocturnal commuters use an internal compass to stay on track.
How to Keep a Wasp from Cheating

It would be easy for fig wasps to cheat. These tiny insects pollinate figs in exchange for a share of the tree's seeds--and theoretically, the wasps could lay claim to more seeds than they deserve. But they don't, and now biologists know why. Parasitic wasps, usually thought of as the bad guys, keep the pollinators honest.
Virus that selectively targets males

Researchers seem to have found a novel virus that is wiping out the male larvae of a Japanese moth, while leaving the females unscathed.
Meet the Beetles--And Their Crazy Family Tree

DNA analysis clears up thousands of beetle relationships and reveals some surprises about their evolution.
Sex "switch" points way to smarter pest control

Turning off a sex "switch" triggered when female insects mate may be a smart and green way of controlling pests in future.
How to make a zombie cockroach

Researchers have worked out the neurological trick used by a species of wasp to turn cockroaches into 'zombie slaves'. The discovery explains why, once stung, cockroaches can be led by a much smaller master towards certain death. Researchers have proven their theory by replicating the effect, and by using an antidote injection to release the cockroaches from their zombie state.
Queen Bees Control Sex of Young After All

Royalty has its privileges, even in the insect world. Queen honey bees can choose the sex of their offspring, a new study shows. Like a sharp stinger, that finding pokes a hole in the notion that queens are merely mindless egg layers and that worker bees have the final say on whether the queen lays eggs that give rise to males or females.
spiders like to leave the lights on

Interesting. I was just reading Amanda's post about the troglobites -- spider-like cave animals that die when exposed to UV light -- and then I came across this. When humans are deprived of sunlight, we lose vitamin D and the calcium that it lets us absorb. It seems that spiders have a reaction to UV deprivation too ...though I wouldn't call it similar.
Celibacy or rickets? Decisions, decisions...
This ties in with Amanda's post.

Brain-damaged bees wandering off?
Hecate submitted, created time 1 year 8 months (www.nytimes.com)
In the US alone, over ninety different crops rely on honeybees for pollination, comprising one-third of the average American's diet and over $14 billion, direct and indirect, of the American economy. But the bees are abandoning their hives, leaving food stores and larvae behind. What gives? (Please, no jokes about this solving our obesity problem.) We can be confident that the bees aren't dying because there are no dead bodies left behind. This article proposes that perhaps a new pesticide caused worker bee brain damage that impaired the bees' celebrated ability to navigate.
