Abstract	The theridiid spider Enoplognatha ovata (Clerck), is a common inhabitant of weedy vegetation along the northeastern seaboard of North America . Recent research into the ecological genetics of color polymorphism in E. ovata in Maine populations (Reillo and Wise 1988a, b, c) has uncovered considerable parasitism of this species by larval Parasitengona mites. Here I' present parasitism frequencies for color morphs of mature female spiders from 15 natural populations . Thirty-five coastal Maine populations of E . ovata were censused during midAugust from 1986-1987. Populations were distributed between Boothbay, ME (43°50' N . Lat./69°37'W, . Long.) and Acadia National Park at Mt . Desert Island (44°25' N. Lat./68°15' W. Long.) (see map in Reillo and Wise [1988b]) . Descriptions of the color phenotypes and life history of E . ovata can be found elsewhere (Seligy 1971 ; Oxford 1976; Wise and Reillo 1985), and censusing techniques for estimating morph frequencies are discussed in Oxford (1976, 1985a, b) and Reillo and Wise (1988b). Spiders were examined for mites in the
