different between aphid vs cantharides

English

Etymology

New Latin aphides, coined by Swedish botanist Carolus Linnaeus in 1758. His inspiration for the name remains unclear. OED suggests a connection to Ancient Greek ??????? (apheid?s, “unsparing, lavishly borrowed”) in reference to the insects' voracity or rapid rate of production, from ?- (a-, “not”) + ???????? (pheídomai, “to spare, be thrifty, be merciful”), ultimately from Proto-Indo-European *b?eyd- (“to split”).
