|State Ranking Justification||
Additional surveys are needed before assigning a state rank. As of 2012, there are five extant occurrences in New York State. Occurrences are known to be in the northern portion of the state and on Long Island, but not in between.
The short-term trends are unknown.
Populations declined in the mid-twentieth century most likely because of increased use of pesticides, metal halide bulbs, and the introduction of parasitoids, such as Compsilura concinnata (tachinid fly) that was introduced in 1906 (Goldstein 2010; Hedbor 2006, Schweitzer et al. 2006).
