Collection and habitat data.

Anotylus insecatus is probably a predator of Diptera larvae in bulbs of onions, tulips, and radishes ( Campbell and Tomlin 1983; Majka and Klimaszewski 2008b). This adventive species has also been found at sap flows and in decaying plant debris ( Campbell and Tomlin 1983) but may also be saprophagous or a scavenger ( Hammond 1976). The New Brunswick specimens were found along river margins in flood debris or in gravel. Adults were captured during May and June.
