Macronyssus crosbyi  has been recorded from several species of bats, mainly Myotis spp., across much of North America (Whitaker & Wilson 1974).

Ornithonyssus bacoti (Hirst)  —tropical rat mite

Ex Rattus  sp.: TN, Blount Co. (Pratt & Good 1954).

The tropical rat mite is widely distributed in the tropical, subtropical and mild temperate regions of the world together with its domestic rat hosts (Radovsky 1985). However, it also parasitizes several other mammals and Whitaker & Wilson (1974) list records from 37 species of mammals in North America alone. This hematophagous mite will bite humans and can cause “tropical rat mite dermatitis” (Durden et al. 1997 b). Ornithonyssus sylviarum (Canestrini & Fanzago)  —northern fowl mite

Ex Iridoprocne bicolor  (tree swallow) nest: 34 F, 1 N, GSMNP, no other data, W. K. Reeves, L­ 3051.

Despite its vernacular name, this blood­feeding mite parasitizes many species of wild birds (Garvin et al. 2004) and some mammals (Whitaker & Wilson 1974).

Ornithonyssus wernecki (Fonseca) 

Ex Didelphis virginiana  (Virginia opossum): 1 F, NC, Swain Co., US 441, 1 Feb. 2006, W. K. Reeves.

Ornithonyssus wernecki  mainly parasitizes the Virginia opossum in North America (Whitaker & Wilson 1974).
