Comments.

Pollock and Majka (2012) reviewed the Nearctic Lacconotus and provided new data on distribution and habitat associations of Lacconotus punctatus . They showed that Lacconotus punctatus is more widespread in eastern North America than previously known. Lacconotus punctatus was reported from mixed forests, an oak savanna, and mature bottomland hardwood forests ( Pollock and Majka 2012, Ulyshen et al. 2010). In NB, this species was found in similar forest types, including a hardwood bottomland woodland, a hardwood bottomland forest on an island, a Populus balsamifera stand near a river, mixed forests with red oak, a red oak forest, and an oak forest near a seasonally flooded marsh. Webster et al. (2012p) reported specimens from a bottomland (silver maple forest), a red oak forest, and a mature red spruce forest with scattered red maple. Most adults were collected early in the season from late May to mid-June, with a few captured as late as early August. Lacconotus punctatus was found at seven new localities in NB and appears to be widespread in the province.

All specimens from NB were captured in Lindgren funnel traps, showing the effectiveness of these traps for detecting this rare species. Interestingly, all but four of the 48 adults of Lacconotus punctatus were captured in the canopy of trees. In a mature bottomland hardwood forest in GA, five of six specimens were captured in flight intercept traps 15 m above the forest floor early in the season ( Ulyshen et al. (2010). They suggested that Lacconotus punctatus might be a canopy and early seasonal specialist and the reason why this species is infrequently collected. Our data support their conclusion.
