Poltys (spider)

Poltys is a genus of orb-weaver spiders first described by C. L. Koch in 1843.[2] Many species are cryptic and are known to masquerade as leaves and twigs during the day,[3] and build an orb web at night to capture prey. The shape of the abdomen which often gives the impression of a rough and broken branch can vary among individuals within a species.[4] The web is eaten up before dawn and reconstructed after dusk.[5]

gollark: Wrong.
gollark: Yes.

gollark: I, personally, blame Macron.
gollark: This is interesting! I'm testing ways to improve the performance/memory use of the Minoteaur inevitable semantic search thing, and it turns out that using a dimensionality reduction thing on the embedding vectors makes some searches turn out identically, and some using rare keywords like "apioform" turn out poorly.
