All rights reserved. This picture of two mating insects comes with an unexpected twist. The one on top is a female, and she has a penis. The one on the bottom is a male, and he has the equivalent of a vagina. During sexual bouts that can last for 40 to 70 hours , she penetrates him and uses her genitals not to deliver sperm, but to collect it. The 3-millimetre-long species is called Neotrogla curvata , and it lives in Brazilian caves.

In This Insect, Females Have Penises And Males Have Vaginas

Yet, as the story of the record-breaking honeybee shows us, females can be just as likely to play the sex game. We know that male animals seek to mate with multiple females to increase their chances of reproductive success. And we think that females are naturally pickier because they invest more energy in producing offspring and do not increase their chances of reproducing by having more than one partner. These are among the most deeply entrenched concepts of evolutionary biology. View image of Are female honey bees really coy? The myth of the ardent, promiscuous male and the coy, choosy female is based on what some have called the Darwin-Bateman paradigm.

The insect that loves having sex

Insect sex may seem fairly simple: fluttering dances, clasping abdomens, a quick mount on a forest floor. But a new review of homosexual insect encounters suggests the acts may not be that straightforward for the individuals involved. Researchers have widely examined homosexual behavior in mammals and birds , but have addressed it less frequently in insects and spiders. To assess the range of evolutionary explanations for same-sex intercourse in the invertebrate world, a team of biologists from Tel Aviv University in Israel and the Swiss Federal Institute of Technology in Zurich, Switzerland examined roughly existing studies on the topic and compiled the first comprehensive review of homosexuality in invertebrates.
You think you're naughty and transgressive? Humans just don't get that freaky compared to insects. An ongoing evolutionary tug of war to control fertilization has led to appallingly rough sexual practices in bugs.
