Comments.

This adventive and cosmopolitan species is found in various stored products such as lima beans, pigeon peas, decaying soybeans, stored grains, fruit, nuts, damp flour, rice, and moldy grass and feeds on surface molds on these items ( Campbell et al. 1989, Thomas 1993). The two specimens from NB were captured in Lindgren funnel traps in the canopy of trees in a mixed forest. This stored product pest is not normally associated with natural habitats. There are a number of farms with barns within 2 km of the site that could have been the source of these specimens.
