According to Gaud and Atyeo (1979), mites of the subfamily Alloptinae are associated with a large number of sandpipers and other waterfowl such as Gaviiformes, Procellariiformes, Pelecaniformes, Ciconiiformes, Anseriformes,
Gruiformes and Charadriiformes.
The habitat of 47.4% of them, including almost all the Anseriformes and Charadriiformes, Gaviiformes, Podicipediformes, and
Gruiformes, consists of a complex landscape of bogs, marshes, lakes, ponds, and streams scattered across tundra on the coasts and inland.
(9,51) Cui (52) suggests that a large number of cross-species transmission events are probably also present in avihepadnaviruses, whose phylogeny does not match that of the host orders
