What are the hosts of the larvae?
Preferred plant hosts for larvae are mostly trees of many species in the family Salicaceae, particularly willows ( Salix spp.) including the exotic weeping willow, and also poplars ( Populus spp.). Members of the elm family Ulmaceae ( Ulmus spp.) and hackberry family Celtidaceae ( Celtis spp.) and less commonly a wide range of species representing a number of other families are also used (Scott 1986). Mature larvae often wander from the original host plant prior to pupation and are often reported from plant species on which they do not feed (Opler and Krizek 1984).

Adult mourning cloaks have been observed infrequently in a number of locations in northcentral Florida and the Florida Panhandle (Jue & Jue 2011, Minno & Powell 2011). Repeated sightings of what appear to be recently emerged adults have been made in certain years (e.g., 2000 and 2011) with no sightings in intervening years. Mourning cloaks may occasionally breed in northern Florida, but most adult specimens found here have been believed to be winter migrants from farther north (Glassberg et al. 2000).
