Dictyestra is a monotypic moth genus of the family Noctuidae erected by Shigero Sugi in 1982. It contains only one species, Dictyestra dissectus, the angle network armyworm, first described by Francis Walker in 1865. It is found from India to Indochina, Sri Lanka, China, Japan, Sundaland and the Philippines and from Sulawesi to the Moluccas and New Guinea.[1][2][3]

gollark: Hmm. I'm not actually sure how to fastly™ do ranking of search results for this.
gollark: I like how crates.io has an excellent collection of highly optimized algorithms for things which I will inevitably use in a ridiculously slow way by accident.
gollark: I'm unsure of exactly where to put the term frequency data, which is important for ranking, or how to rank based on word nearness whatsoever.
gollark: I found an efficient and fairly low-storage way to store some of the inverted index data (specifically "does this term occur or not").
gollark: Maybe it could index conespace too.
