"form in the life-cycle of butterflies, moths, etc., between larval and adult, consisting of a dormant pupa in a hard outer case," also the case itself, c. 1600, from Latin chrysallis, from Greek khrysallis (genitive khrysallidos) "golden colored pupa of the butterfly," from khrysos "gold" (see chryso-), + second element meaning something like "sheath." Seeking a plural, OED leans toward the classically correct chrysalides."
adjectival word-forming element, especially in zoology, "belonging to, connected with, member of a group or class," in some cases probably via from French -ide, back-formed from Modern Latin names of zoological classes in -idae, as arachnid "a spider" from the biological class name arachnidae.
This -idae is the plural of Latin -ides, a masculine patronymic (indicating "descent from"), from Greek -ides "son of," denoting descent from the person to whose name it is attached (such as Heraklides).
In astronomy, of meteor showers, "having its radiant in" the constellation named (Perseid, Leonid, etc.), it probably represents Latin -idis, from Greek -idos, the genitive of the feminine form of the patronymic suffix.
