The Spitting Spider
The species of spider known as Scytodes kills its victims by squirting a mixture of toxin and gluey substance over them. These liquids are produced in an enormous gland substance over them. These liquids are divides into two compartments: one contains a toxin, the other a gluey substance. The spider contracts the muscles surrounding the latter and a stream of glue is rapidly ejected from the animal's fangs. Sprayed out in a twig it happens to be traversing. Then having immobilised its prey and stuck it on to branch or leaf, it can eat it later where it hangs.
Pasilobus' Trap
Pasilobus, only to be found in New Guinea, is a great expert at preparing traps. The webs it spins are very sticky. The whole web is slung between two fixed points. The knot at one end is very tight, but the one at the other end is left quite loose. This is not a mistake, and is not a result of the spider's not concentration. That this is a hunting strategy can be seen when the prey approaches. When a moth flies into the web, the loose loop end becomes detached. Because the other end stays fastened, the insect remains hanging like a bundle in the air. Later the spider approaches it and sprays a sticky material all over it, starting from the head. In this way the spider catches its preys alive.
