Summary

Did you know?

Richard's fungus moth is named after Dr. A.G. Richards, Jr., who first collected the species in 1929 in Georgia (Brower 1941).

State Ranking Justification

There is only one documented population of Richard's fungus moth in New York State, but the species could be more widespread. Throughout its range, the species seems to be more common than previously thought (NatureServe 2010). Its status and distribution in New York State is not well known.

Short-term Trends

The short-term trend for Richard's fungus moth in New York State is unknown. The one documented population in the state was surveyed only in 1995. However, the species is thought to be stable in most places. It appears to be increasing in southern New Jersey (NatureServe 2010).

Long-term Trends

The long-term trend for Richard's fungus moth in New York State is unknown. It may be increasing as a result of oak-kill by gypsy moths, since the larvae of Richard's fungus moth feed on fungi, probably on dead trees (NatureServe 2010).

Conservation and Management

Threats

The threats to Richard's fungus moth are uncertain. Elimination and fragmentation of habitat by commercial and residential development are probably the greatest threats to the species. Otherwise, there are no apparent threats (NatureServe 2010).

Conservation Strategies and Management Practices

Maintaining suitable habitat, forests, is the main management need.

Habitat

Habitat

Richard's fungus moth seems to occur mostly in rather ordinary dry-mesic to swampy hardwood forests. It may be more common in areas with a lot of dead oaks (NatureServe 2010). In New York State, it is known to occur in a pitch pine-oak forest.

Range

New York State Distribution

Richard's fungus moth is known to occur on Long Island.

Global Distribution

Richard's fungus moth is known to occur from Martha's Vineyard, Massachusetts, to South Carolina and perhaps Florida, west to Kentucky (Covell 1984).

Best Places to See

  • David A. Sarnoff Pine Barrens Preserve (Suffolk County)

Identification Comments

Identifying Characteristics

Richard's fungus moth is a small moth with a wingspan of 15-17 mm. It has yellowish wings that are patterned with light and darker brown shading. The hind wings are much paler than the forewings (Covell 1984). For a more detailed description, see Brower (1941). Larvae (caterpillars) of fungus moths (Metalectra species) lack prolegs on abdominal segments A3 and A4; have rough skin; have a white, cream, or tan background; and are often found on bracket fungi and other fungi (Wagner et al. 2008).

Best Life Stage for Proper Identification

The adult is the best life stage for identification.

Behavior

In southern New Jersey, there are two broods each year. Presumably pupae hibernate (NatureServe 2010).

Diet

Larvae of fungus moths (Metalectra species) are believed to feed on fungi, such as bracket fungi, on trees (NatureServe 2010). They seem to prefer bracket fungi and other fungi with long-lasting fruiting bodies (Wagner et al. 2008).

Best Time to See

The best time to see Richard's fungus moth is during its flight season, from late May-August (Covell 1984). In New York State, adults have been captured in mid-late July. Similarly, from 1931-1941 in Massachusetts, 13 specimens were collected in July (Brower 1941).
