Male flies with mutations in the fruitless gene display altered sexual behavior. Fruitfly courtship, which involves a complex male-initiated ritual, may be disrupted in many ways by mutated fru alleles; fru is necessary for every step in the ritual. Some alleles prevent courting entirely, while others disrupt individual components.
Sexual coercion among animals is the use of violence, threats, harassment, and other tactics to help them forcefully copulate. [1] Such behavior has been compared to sexual assault, including rape, among humans. [2] In nature, males and females usually differ in reproductive fitness optima. [3]
Female waltzing flies that fed on ejaculate also had higher survival than flies that did not feed on ejaculate. [7] Ejaculate feeding has been suggested as originating from sexual conflict. [7] Waltzing fly females typically only mate once, and the sperm may have evolved to ensure the waltzing fly male's paternity by preventing multiple mating.
The Poecilobothrus nobilitatus is a popular fly for animal study because of its relatively large size, evident sexual dimorphism in wing markings, and its courtship and hunting displays on a 2-dimensional surface (water), allowing for more accurate and easy studying of the species. [6]
The prevalence of sexual cannibalism gives several species of Latrodectus the common name "black widow spider". Sexual cannibalism is when an animal, usually the female, cannibalizes its mate prior to, during, or after copulation. [1] This trait is observed in many arachnid orders, several insect and crustacean clades, [2] gastropods, and some ...
"Thornhill introduces this theory by describing the sexual behavior of scorpionflies. In which the male may gain sex from the female either by presenting a gift of food during courtship or without a nuptial offering, in which case he rapes her."
An online gaming dispute made its way to the real world when a New Jersey man flew to Florida to attack another player with a hammer, authorities said. Edward Kang, 20, is charged with attempted ...
An autopsy showed no signs of previous fractures, illness or drugs, but the child was malnourished. Specimens of Muscina stabulans (false stable fly) and Fannia canicularis (lesser house fly) were recovered from the genital area of the corpse. These particular flies are attracted to urine and/or feces much more than corpses.
