Peacock Spider

This is a kind of jumping spider, and it’s only about 5mm in size. The males have a colorful pattern on flaps that extend from their abdomen during breeding/mating. In addition to this, they raise their back pair of legs and dance from side to side to win over their plain brown females.
Only found in Australia, they were classified as species Maratus volans because people originally thought the flap was for gliding after jumping. Wiki

Face vs. Body
There have been many studies about what body part attracts the opposite sex, but few studies that compare the importance of body parts to each other. A new study suggests that people assign more importance to faces than bodies when they are looking for a long-term relationship. For a potential short-term relationship, men assigned slightly more importance to the appearance of a woman’s body, while women cared more about a man’s face.
Statistical analysis of men rating women indicated that, even though both the body and face ratings were significant positive predictors of the ratings given to the combined images, the face ratings were stronger predictors of the combined ratings. It was also observed that the ratings for combined images was slightly higher for short term relationships as compared to long term relationships. One other significant observation – when the short term and long term relationship data were analyzed separately, the body ratings stood as more significant predictors to the combined ratings than face ratings, for short term relationships. In the case of females rating men, similar to men – the body and face ratings were both significant predictors with the face ratings being very strong predictors as compared to the body ratings. However, females ratings for men did not show any difference under the short term and long term decisions.
This only makes sense, as we tend to cover our bodies most of the time, but you have to look at that face a lot. Link -via Digg

Orgy on the Beach (for Horseshoe Crabs, Silly!)
If you live near the Delaware Bay shore, you can go there to witness one heck of a beach orgy happening now: thousands of horseshoe crabs are piling on top of one another mating …
On the Delaware Bay shore, there’s a swinging party that’s been taking place for millions of years.
If you’re a female horseshoe crab, then it’s your night. You’ll swim to shore, meet a special someone and he’ll clasp onto the back of your shell. You and he will crawl onto the beach together, where you’ll spawn at high tide under the light of the full moon.
But the mate attached to your shell is not your only tryst. On this night, you will mate with up to 13 males, all at the same time. Thousands of horseshoe crabs will pile on top of one another, glistening shells covering the beach for miles.

Lady Chimps will Mate for Meat
Researchers in the Tai National Park in West Africa found that in a study of 262 chimpanzees, male chimpanzees favored giving food to females that were in heat and ready to mate:
Gomes and co-author Christophe Boesch observed all of this while studying wild chimpanzees in the Tai National Park at the Cote d’Ivoire, West Africa. The chimp group — consisting of 49 individuals total — included five adult males and 14 adult females, which were the focus of the study published in the latest PLoS One.
The researchers recorded 262 male to female meat transfers, with the meat mostly coming from red colobus monkeys. Chimps also kill other types of monkeys, duikers and small mammals.
Gomes and Boesch collected data on matings, observing the same number — 262 — during times when females were in estrous. The scientists noted that males would share with all types of females, whether in estrous or not, although the former received preference.
“After all,” Gomes said, “males double their mating success by sharing meat with females, and this is a potentially enormous benefit.”

How Mosquitoes Find Love
How do mosquitoes find love? Turns out, they serenade their mates! Scientists at Cornell University found out by supergluing mosquitoes on to a tiny tether and then suspending them in the air:
The male mosquito’s buzz, or flight tone, is normally about 600 cycles per second, or 600-Hz. The female’s tone is about 400-Hz. In music, he’s roughly a D, and she’s about a G. So the male brings his tone into phase with the female’s to create a near-perfect duet. Together, the two tones create what musicians call an overtone — a third, fainter tone at 1200-Hz. Only then will the mosquitoes mate.
