Chrysotus

Chrysotus is a genus of flies in the family Dolichopodidae.[4] It is one of the largest genera in the subfamily Diaphorinae, with more than 460 species.[5][6] However, the genus is probably paraphyletic, and possibly even polyphyletic, with respect to several related genera such as Achradocera, Falbouria and Lyroneurus.[6][7]

gollark: If they had more memory, you could probably run a higher level spellcode interpreter on them.
gollark: CPUs would basically be "able to load multiple programs and run self modifying code", loosely defined.
gollark: I suppose if the summoning stones are ASICs, the magic circle things are FPGAs, and actual general purpose CPUs will probably come later.
gollark: Nullity.
