(1956) On some Coccinellidae from Newfoundland and Nova Scotia. (1999) Vertical and temporal distribution of Coccinellidae (Coleoptera) in flight over an agricultural landscape.
The potential vulnerability of the coccinellid fauna is discussed in the context of both adventive species in the region, and habitat loss and conservation.īoiteau, G., Bousquet, Y., & Osborn, W.P.L. Biogeographic observations are provided in relation to the composition of the fauna as a whole, and of disjunct populations of six Nova Scotia coccinellids, several of which appear to be members of a coastal plain fauna that extends from New England to southern Nova Scotia. Collecting effort in the three provinces and their sub-regions is briefly analyzed and compared. Records of two adventive species not established in the region are also reported. Didion punctatum (Melsheimer) is removed from the fauna of PEI, and Coccidula lepida LeConte is removed from the fauna of NS, and Scymnus impexus Mulsant is removed from the faunas of NS and NB. Two species, Diomus amabilis (LeConte) and Naemia seriata seriata Melsheimer, are newly recorded in Canada. Of these, records are provided for 13 species newly recorded from Nova Scotia and 14 from Prince Edward Island. The known fauna of the region consists of 47 species: 41 in Nova Scotia, 39 in New Brunswick, and 21 in Prince Edward Island. New records of Coccinellidae in the Maritime Provinces of Canada are reported.
