Did you know?

Apamea inordinata is included in a group of moths composed largely of North American apameine and noctuine Noctuidae. Most moths in this group are strong fliers. Individuals can easily travel a kilometer in half an hour, and 10 kilometers in a night.

State Ranking Justification

Forbes (1948) reported that this moth was extremely local. There are only two recent records of the moth in New York despite much trapping effort on the east end of Long Island near historical localities.

Short-term Trends

The short-term trend for this species in New York State is unknown. One individual was documented on one occasion on Robins Island in 1997. The species was also captured on eastern Long Island in 2007.

Long-term Trends

The long-term trend for this species is unknown. Forbes (1948) reported that the moth was extremely local. Despite much trapping effort on the east end of Long Island near historical localities, there are only a few recent records of the species.

Conservation and Management


The threats to this species in New York State are uncertain. Elimination and fragmentation of habitat by commercial and residential development are probably the most significant threats to this species.

Conservation Strategies and Management Practices

Minimizing lighting to maintain dark sky conditions would be beneficial.

Research Needs

Additional inventory is needed at suitable habitats (dry, often sandy, areas with grasses and/or sedges). Surveys should be conducted at blacklight at night from June to July.



This moth is found in dry, often sandy, areas that contain grasses and/or sedges.

New York State Distribution

Currently, the only known occupied sites are on eastern Long Island and a nearby island. The moth is historically recorded from the eastern part of Long Island and Charlotte, New York.

Global Distribution

Distribution data for U.S. states and Canadian provinces is known to be incomplete or has not been reviewed for this species. The species is known to occur in North America in New York, Pennsylvania, Wyoming, Ontario, and Quebec (NatureServe 2010).

Best Places to See

  • Napeague State Park (Suffolk County)
