Spindelien

Spindelien is a hypothetical genus of spiders used in speculative biology and worldbuilding. The term is employed to explore how spindle-shaped bodies and specialized silk might evolve in arboreal spiders. It is not a recognized real taxon and has no formal standing in zoological nomenclature.

Etymology and morphology: The name combines the German spindel meaning "spindle" with the -ien suffix found in fictional taxa. Descriptions place adult spindelien at roughly 6–12 mm, with an elongated, spindle-shaped abdomen, long slender legs, and variable coloration. Silk glands are proposed to produce a dense, resilient thread.

Ecology and behavior: In imagined ecosystems, spindelien inhabit temperate forests and field margins, constructing multi-layered webs that blend orb and funnel forms. They are primarily nocturnal and prey on flying insects and small arthropods. In simulations, their silk supports their nests and enables efficient prey capture.

Life cycle and reproduction: Mating involves seasonal courtship, followed by female egg sacs containing dozens to hundreds of embryos. Spiderlings disperse by ballooning and reach maturity after several molts; in temperate models, lifespans span roughly one to two years.

Significance and limitations: Spindelien serve as a teaching and worldbuilding tool for discussing morphology, biomechanics, and silk properties without implying real species. As a fictitious taxon, it lacks conservation status and any authority recognizing it scientifically.
