Cupiennius Coccineus comes under Species of the Cupiennius banana spider. This is an arboreal spider found in Costa Rica. Fishing Spiders (Trechaleidae) can be found in the family Coccinianae. Cupiennius Coccineus has a dark pattern on the ventral side as opposed to other species in the genus. It belongs to the banana spider species Cupiennius. Spiders found in Costa Rica are arboreal. This species is characterized by red spots under its legs.

Known range of Cupiennius Coccineus - Costa Rica to Colombia  

Males are 22 to 26 mm in length and females 27, 38 mm. Over 100 millimeters of leg span is possible. Cupiennius coccieus is therefore one of the larger species of the genus. According to the sex staining, the type is quite variable. Each sexe has the same basic color: brown. There is a conspicuous red warning color on the underside of the femora of the front pair of legs of the female, which is meant to show a threat to a predator in case of danger. The male animal lacks this quality. Cupiennius coccineus is the only species of Cupiennius without a ventral drawing. 

There are several species of Cupiennius that are equally large, including the large wandering spider (C. salei), Cupiennius getazi, and Cupiennius chiapensis that are often mistaken for Cupiennius coccineus. Colors vary among species, however. The genus Phoneutria, as well as species of the family of the comb spiders (Ctenidae), can also cause confusion among humans.

Cupiennius coccineus Way of life

The cupinus coccineus penguin, predominantly nocturnal, prefers to hide in suitable locations, commonly near bananas and bromeliads, during the day. In such crevices, she seeks shelter from the rain. Additionally, filaments can be used to join leaves together to form nooks. Often found on the same plants as Cupiennius getazi, Cupiennius coccineus shares many habitats with this species.  As a stalker, it hunts arthropods at night and preys on small vertebrates including reptiles and amphibians. Based on their calls, female Cupiennius coccineus is said to have located males during observations. Because the spiders are blind, they detect vibrations generated by croaking on the nearby vegetation, which are then picked up by their fissile sensory organs. Spiders could find frogs with this technique. 

Cupiennius coccineus Reproduction

Cupiennius coccineus has similar reproductive behavior to other species in the genus. In order to attract a male, a sexually mature female uses pheromone-coated filaments. By way of the opisthosoma, the female is able to identify and identify the threads that identify it and begins a dance to court them. The male can often repeat this behavior several times throughout an hour-long courtship. If a female is willing to mate, she will shake her opisthosoma in response to the courtship. The male climbs on the back of the female and alternates inserting the bulbs into her spermatheque. When the eggs in the female's opisthosoma mature, its swelling causes her need for food to increase significantly. She forms her first egg cocoon three weeks later, which is carried by her spinneret. They hatch out of the cocoon for about a month, and the female has already woven a web around them. The young hatch after a month and leave the web a week later. Besides the brood, females can make up to three more cocoons. Spiders grow to a size of eight to ten millimeters within eight to ten months after being born. Compared to males, females of Cupiennius coccineus are much longer-lived.
