Fig. 13.—Exit holes of small, four-winged, wasplike parasites of Lyctus in powder-posted red oak interior finish. (Original.) Many species of small, four-winged, wasplike parasites have the Lyctus beetles as their hosts. The emergence or exit holes of the adult parasites (fig. 13) are much smaller than those made by the beetles, but are often mistaken for those made by young Lyctus larvse. ^ Histeridae and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Craighead, Frank C.
