Kannustiiva (Kannustiib)

Two sorts: jalaka-kannustiib, the white letter hairstreak, Strymonidia w-album; and toominga-kannustiib, the black hairstreak butterfly, S. pruni. Part of a swarm of butterflies in the Lepiku District. Why are their young called caterpillars and not buttermaggots? (Actually, the word comes from Old French: chatepelose, hairy cat, reminiscent of woolly bears, see Piksepeni), later modified by the verb piller, to pillage, plunder, reflected in the Estonian name: röövik, plunderer, robber, etc.). See also Kedriku.
