The fruitless gene (fru) is a Drosophila melanogaster gene that encodes several variants of a putative transcription factor protein.Normal fruitless function is required for proper development of several anatomical structures necessary for courtship, including motor neurons which innervate muscles needed for fly sexual behaviors.

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]
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.

Syritta pipiens flies at a very low height, rarely more than 1 m (3 ft 3 in) above ground. [8] Adult flies sometimes cruise around ignoring other flies, but males sometimes turn towards other flies, circle around them and make sudden darts if they are females, attempting to force copulations with them.

"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."
Due to rape or sexual assault, or the threat of, there are many resulting impacts on income and commerce at the macro level. Excluding child abuse, each rape or sexual assault costs $5,100 in tangible losses (lost productivity, medical and mental health care, police/fire services, and property damage) and $81,400 in lost quality of life.

Formicophilia, a form of zoophilia, is the sexual interest in being crawled upon or nibbled by insects, such as ants, or other small creatures. [1] [2] This paraphilia often involves the application of insects to the genitals, but other areas of the body may also be the focus.
