Injektoreina

Injektoreina is a genus of small, hairy spiders that belong to the family Uloboridae. These spiders are found in the tropical and subtropical regions of the Americas, with species ranging from Mexico to Argentina.

Injektoreina spiders are characterized by their small size, typically measuring between 2-5 millimeters in body length. They have a distinctive appearance, with a hairy abdomen and tibia. Their legs are long and thin, with a mix of orange and black hairs on the femur. Adult spiders have a yellowish-orange color, becoming more brown with age.

These spiders are considered harmless to humans and are not known to produce venom capable of causing significant harm to mammals. Injektoreina are primarily nocturnal and tend to hide during the day in protected areas like under rocks or tree bark. At night, they come out to hunt small prey such as flies, mosquitoes, and ants.

Injektoreina spiders use a method called 'ballooning' to disperse sperm across distances. They release a thread of silk, which is then attached to vegetation by the spider. This acts as an anchor for the spider, allowing it to project the sperm thread to produce webbing that can advance and save new spaces.

The species and classification of Injektoreina are subject to ongoing research. There are reports of several species based on morphological characteristics and sampling sites, but more detailed study and molecular analysis are needed to conduct a more comprehensive recognition of these organisms.
