Marsh Fern Moth
Fagitana littera (Guenée, 1852)
Insects

Threats [-]
The most immediate threat is invasive plants such as purple loosestrife (Lythrum salicaria) and common reed (Phragmites australis), although for some acidic bogs this may not be a threat. Mosquito spraying could be a threat in New York. It is very unlikely modern gypsy moth (Lymantria dispar) suppression programs would target habitats for this moth and even less likely that Bt (Bacillus thuringiensis - a bacterial l control used on gypsy moth caterpillars) would impact larvae in June and later. While populations near Orient, Long Island were eradicated by annual burning (Latham 1953) this is not likely to be a threat today.

Conservation Strategies and Management Practices [-]
Keep the habitat open and control invasive plants. Deer will not likely negatively impact this species because of the foodplant and habitat that it occurs in.

Research Needs [-]
Documenting the foodplants used by this species, in addition to Marsh Fern (Thelypteris palustris) would facilitate inventory. The old records from the Adirondacks require further investigation.
