Habronattus pyrrithrix

Habronattus pyrrithrix is found in grassy areas covered in plant material or by bodies of water. They feed on various prey, including flies, caterpillars, aphids, and other spiders. They display a color preference when foraging by avoiding yellow or red-colored prey. This may be because red and yellow colors are linked with prey that are capable of utilizing chemical defenses, such as ladybugs, and may be harmful if consumed by predators. == Mating and Reproduction ==

Sexual dimorphism Habronattus pyrrithrix displays sexual dimorphism with respect to their size and coloration. Male H. pyrrithrix display bright condition-dependent coloration with distinct red faces and green legs. to females during courtship. Males will court whatever females they encounter, which can lead to aggression by females from other species. Sexual selection favors the distinct coloration and morphologies found in males and drives the diversification of this species from others in the genus. when courting females, including complex movements, vibrations, and signals on top of their distinct coloration. Females tend to move around during a male's courtship display, which may be why males rely on more than just visual displays to capture a mate's attention. Males then produce substrate-borne vibrations, along with leg flicks, by striking their abdomen against the substrate they are on, which produces vibrations or seismic signals sensed by the females. If females seem receptive and safe to approach, males then mount and engage in copulation. The combination of visual and substrate-borne displays increases male reproductive success and decreases cannibalism by unimpressed females. Sexual cannibalism in this species is a form of sexual conflict in which the males do not gain any benefits from being eaten by the females. Only the females benefit from this conflict as they are able to gain a source of nutrition, while the males cannot pass on their genome. Therefore, it is beneficial to the males to successfully court females so that they are receptive to them. In some instances, females may show higher aggression toward the males they deem are in better condition; these aggressive behaviors could be another way in which females assess the quality of the male and their ability to overcome the risk that comes with mating. This combination of displays also reduces the courtship time, allowing the individuals to choose mates quickly and spend less time exposed to the risk of predation. == Predator Deception ==

Males risk predation when they are searching for mates or engage in courtship behaviors. Accompanied by their bright coloration, this increased movement in open habitats places males at a higher risk of gaining predator attention. Males combat this risk with their clearly visible dorsal patterns. These patterns are not used for courtship displays and are not bright in coloration. H. pyrrithrix males display these dorsal patterns in addition to leg-waving to mimic the antennas of wasps or bees and deceive predators. The higher rates of movement in males versus females preserve the evolution of cryptic dorsal coloration in both individuals. Further studies on non-display colorations and predator deception in Habronattus could provide a look into the evolution of diverse color patterns. ==References==
