Orsinome vethi is a species within the genus Orsinome, which is part of the orb-weaver spider family (Araneidae). Orb-weaver spiders are known for their impressive, intricate webs which they use to capture prey. Orsinome vethi, like other orb-weavers, likely constructs large, circular webs with radial designs. These spiders are known for their ability to rebuild their webs daily if necessary. The genus Orsinome is characterized by spiders that often have brightly colored and patterned bodies, which can serve both for camouflage and mate attraction.

Other Information
Venomous?
Orsinome vethi is venomous, as are all orb-weaver spiders, using its venom to immobilize prey that becomes caught in its web. However, the venom of Orsinome vethi is not considered dangerous to humans, typically causing no more than minor symptoms such as localized pain or swelling in the event of a bite.
A Danger to Humans?
There is minimal danger to humans from Orsinome vethi. These spiders are not aggressive towards humans and tend to avoid encounters. Bites from orb-weaver spiders are rare and not considered medically significant.
Population Status
Specific data on the population size and distribution of Orsinome vethi is limited. However, orb-weaver spiders tend to be common in suitable habitats, suggesting potentially stable populations where environmental conditions are favorable.

Life Span:
The lifespan of orb-weaver spiders, including those in the genus Orsinome, can vary but generally spans about a year, allowing them to complete a cycle of mating, egg-laying, and the emergence of new spiders within a single season.
Weight and Length:
Orb-weaver spiders can vary in size, with many species featuring body lengths that do not typically exceed a few centimeters. Specific measurements for Orsinome vethi may depend on age, sex, and environmental factors.
Distribution:
Orsinome vethi is found in India, China, Vietnam, Laos, Malaysia, Indonesia (Sumatra, Java, Bali, Flores).
Habits and Lifestyle:
These spiders are primarily nocturnal, constructing or repairing their webs at night to catch prey. During the day, they may hide in nearby foliage or retreats.
Diet and Nutrition:
Orsinome vethi preys on insects and other small arthropods that become ensnared in its web. The size and structure of the web allow it to capture a variety of prey.
Mating Habits:
Mating behavior in orb-weaver spiders involves complex rituals, with males often needing to approach females with caution to avoid being mistaken for prey. After mating, females lay eggs in silk egg sacs, which are often placed in protected areas near or in the web.
