COVER: Female of the seed bug Cordillonotus stellatus Scudder (Heteroptera: Lygaeidae) [Total length 4.90mm] . A potentially rare and endangered insect, in Canada known only from two females, one from Summerland and one from Victoria. Also reported from California, Oregon and Washington (Scudder, G.G.E. 1984. Can. Ent. 116:1300). Original pen and ink drawing by Edie Bijdemast, reproduced by permission of the Canadian Entomologist.

COVER: Male Cybaeus multnoma Chamberlin and Ivie (Araneae, Cybaeidae) drawn by Robb Bennett. Scale bar = 2 mm. Individuals of about two dozen species of this Holarctic genus are dominant generalist predators in the forest floor arthropod community of the Pacific Northwest especially in coastal regions. Six species are known to occur in British Columbia. Cybaeus reticulatus Simon and C. morosus Simon are abundant in a variety of coastal habitats from San Francisco to the outer Aleutian Islands (in the Queen Charlotte Islands the former is found from sea level wet forests to alpine meadows). Cybaeus signifer Simon and C. eutypus Ch. and Ivie are very common in south eastern B.C. They range from mid-coastal B.C. south to Big Sur and the Yosemite area (C. signifer) and from the Queen Charlotte Islands to mid-coastal Oregon and the Willamette Valley (C. eutypus). Two other species have more restricted ranges: C. sinuosus . Fox is apparently endemic to the Canadian Rockies in Banff, Jasper, and Yoho National Parks and a new species is found in south central B.c. and adjacent Washington from Lillooet through the Okanagan Valley to Okanogan County. Many species of Cybaeus (most notably in Japan, California, and Oregon) have extremely restricted ranges and are known from only a few specimens. From: Bennett, R.G. 1991.

COVER: An adult female Dytiscus dauricus Gebler (Dytiscidae: Coleoptera) drawn with pen and ink by David Young from specimens collected by Adrian de Bruyn. The specimen is 33 mm long. The species is Holarctic in distribution and can be collected along the margin of ponds, slow brown water streams and bush- or tree-ringed permanent ponds and lakes in British Columbia.

COVER: An adult female Hyalophora euryalus kasloensis (Cockerell) (Lepidoptera: Saturniidae) drawn with pen and ink by Sheri Giesbrecht from specimens reared by Dean Morewood. The ceanothus silkmoth, Hyalophora euryalus (Boisduval), is native to the Pacific coast and western mountains of North America from Baja California to British Columbia. Despite any nominal preference for ceanothus, larvae of this species have been reported to feed on a wide variety of broad-leaved trees and shrubs and at least one conifer. In mid to late summer the larvae spin sturdy tear-drop shaped cocoons, usually attached at the side to twigs of their host plant, within which they spin a second cocoon. After overwintering as diapausing pupae, the large reddish brown moths emerge from their cocoons mainly in May and June, and dedicate their one week adult lifespan to reproduction. The form known as H. e. kasloensis is found in the interior of B.C. and northern Washington and Idaho and shows a distinct larval phenotype, but its taxonomic status has yet to be firmly established (see p. 31).

COVER: The larva of the widespread western dragonfly Sympetrum madidum (Hagen) was first described by Rob Cannings from specimens he collected in Victoria and the Chilcotin (see Pan-Pacific Entomologist 57(2):341-346, 1981). The species lives in shallow ponds, often those that dry up in summer. It ranges from the Northwest Territories south through British Columbia to California and east to Manitoba and Missouri. The adults of the genus Sympetrum are a common sight in British Columbia from May through October, but are especially evident in the late summer and fall. Most are reddish; S. madidum can be identified by its white thoracic stripes and the venation of its orange-tinged wings. The pen and ink drawing is by Rob Cannings.
