Fun Net Casting Spider Facts For Kids
Gallery
Have you ever heard of the net-casting spider? This unique insect is also known as Deinopidae and was first written about by Carl Ludwig Koch, a German entomologist, in 1850.
Net-casting spiders are native to Australia, Africa, and the USA. There are two genus types based on the structure of their body, Deinopis (Ogre-faced Spiders) and Menneus (humped back Spiders). Avella and Avellopsis are the earlier genera that are grouped under Menneus lately.
These spiders have a quirky way to capture their prey by forming a tiny cribellate silk web through their front legs. They can expand their web by two or three times to capture the insect passing by.
Net-casting spiders possess a long, twig-like body, stretched legs, and eight eyes, two of which are massive and situated at the front portion of the head (Ogre-faced). These big eyes enable the spider to be active during the night effectively. Male net-casting spiders are smaller than females. The net-casting spider species are abundantly available.

How do their webs work?
Net-casting spiders sway from the plants with their heads pointing downwards to look for prey. They will form silky nets held by their front legs and supported by their back legs.
This net-like cribellate silk web will be a mix-up of white and blue. Though the silk web is not sticky, the silk web grids are designed to smoothly expand and entwine the insects.
They emit white facial droplets onto the foliage. When the insects come nearer to the silk web, they will jump strong onto it, entangle them, making sure they cannot move and shake further and eat them comfortably.
The silk web that has not been used for seizing prey overnight is either left as is to catch the prey the next night or might be eaten by the net casting spider themselves. The approximate time to build their silk web would be half an hour.
How do Net Casting Spiders use their venom?
Ogre-faced net-casting spiders have tender venom that is not poisonous to humans. Instead, the venom is used for catching insects.
