Goes pulcher
Living-hickory Borer
Goes pulcher is a wood-boring beetle in the family Cerambycidae, commonly known as the Living-hickory Borer. First described by Haldeman in 1847, it develops in living hickory (Carya) and pecan (Carya illinoinensis) trees. Larvae tunnel beneath the bark, damaging cambium and sapwood. The species has a 2-3 year life cycle and is distributed across Canada and the United States.
Hylurgopinus rufipes
Native Elm Bark Beetle
The native elm bark beetle is a small scolytine weevil and principal vector of Dutch elm disease in the northern Great Plains and prairie provinces of Canada. Adults are brownish-red, measuring 2.3–2.9 mm, and complete one generation annually. Overwintered adults emerge in spring to colonize weakened or dying American elm, constructing egg galleries in the inner bark where larvae feed on cambium tissue. The species exhibits distinctive acoustic communication: males produce simple multipulse calls, stress/rivalry chirps, and bimodal premating stridulation at gallery sites, while females do not stridulate. Males become strongly arrested at attractive female galleries and engage in brief contests with rival males shortly after a resident male establishes presence.
Saperda candida
Round-headed Apple Tree Borer
Saperda candida is a longhorned beetle (Cerambycidae) native to North America. It is a significant pest of trees in the rose family (Rosaceae), particularly apple, pear, hawthorn, and crabapple. The species was described by Fabricius in 1787 and occurs across Canada and the eastern United States. Its larvae are roundheaded borers that tunnel beneath bark and destroy cambium tissue, often killing young or stressed trees.
Saperda lateralis
Red-edged Saperda
Saperda lateralis is a longhorned beetle in the family Cerambycidae, first described by Johan Christian Fabricius in 1775. It is broadly distributed across eastern North America, ranging from Canada through the eastern United States. The species is associated with several tree hosts, particularly maples, and is known to attack stressed or declining trees. A distinctive subspecies, S. lateralis rileyi, was described in 2010 from the lower Mississippi Delta region based on consistent morphological differences and partial geographic separation from nominate populations.
