The average Filament Spider is about 3m across with legs fully spread, with a body of about 0.5m. Their back legs are long and bent, like that of a cricket, and are used to pull and shape their filament webbing, as well as to hang and leap.
They have a membranes under their forarms to help with gliding, but will typically create wings from their plastic.
Lancer
Lancers are Filament Spiders ambush in packs of 5-10, and will position themselves advantageously to throw javelin spears at their prey.
Garrotes
Surprisingly fast and nimble, Garrote Spiders thread their hunting grounds with barbed lines of filament rope that they will then attempt to snare prey in by throwing nets at them or running around them in circles with the line in tow.
Pitfalls
Made by creating a thin and brittle web over a deadly drop, which the Spider will then cover in leaves and dirt
The Filament Spider's primary defense is to never be seen at all. These ambush predators do not attack until their prey has worn themselves out on the sticky and reactive cabling of their webbing, and can remain suspended in difficult to reach places for long times due to their light weight, hooked appendages, and the ability to lock their carapace into position so that they do not tire of the positioning.
Range
Filament Spiders convert large swaths of land into hives up to a kilometer in width, with a spacing of twice that to leave room for prey species to breed. Typically, these hives live in harmonious superhives, with the excess members of each hive migrating outwards and joining with the broods of other hives to make new hives, but from time to time an advantageous adaptation will make one of the hives so competitive that their interactions with the other hives becomes competitive, triggering a hive war.
Instigating hive wars is the primary means Exterminators have to keep the filament spider population in check.
