Aphidecta obliterata
larch ladybird, larch ladybug, Larch Lady Beetle
Aphidecta obliterata is a small ladybird beetle (3.5–5 mm) native to Europe, with introduced populations in North America. It is a specialized predator of conifer-infesting aphids and adelgids, particularly associated with spruce and larch. The species exhibits remarkable color polymorphism, ranging from tan to brown with pinkish tints to nearly black. Multiple unsuccessful attempts were made to introduce it to eastern Canada as a biological control agent for the balsam woolly aphid (Adelges piceae) beginning in 1941. Females demonstrate sophisticated oviposition behavior, using conspecific larval tracks and egg-surface chemicals to avoid sites with high cannibalism risk.
Brumus quadripustulatus
Cream-spot ladybird, Cream-spot lady beetle
Brumus quadripustulatus is a small ladybird beetle native to Europe and northern Asia, now established in North America. It is recognized by its distinctive cream-colored spots on a dark, nearly black background. The species inhabits various wooded and shrubby environments and has been observed preying on aphids and scale insects.
Calvia quatuordecimguttata
cream-spot ladybird, cream-spotted ladybird, polkadot ladybird, eighteen spot ladybird
A small Holarctic ladybird measuring 4–5.5 mm, highly variable in coloration across its range. In Europe it appears maroon-brown with fourteen cream spots; in North America and eastern Asia, color forms range from black with white spots to yellow or pink with eighteen large blotches. It inhabits deciduous woodlands, hedgerows, and ruderal areas, overwintering in bark crevices and leaf litter.
Coccinella hieroglyphica
Hieroglyphic Lady Beetle, Hieroglyphic Ladybird, Hieroglyphic Ladybug
Coccinella hieroglyphica is a Palearctic lady beetle species associated with heath and moorland habitats, particularly on Ericaceae plants. It is distributed across northern Europe, extending beyond the Arctic Circle, through Russia and Siberia to East Asia. The species is aphidophagous, with populations showing considerable annual fluctuation. Adults are active from May through October and overwinter in coarse woody debris beneath pines and birches.
Coccinella undecimpunctata
eleven-spot ladybird, eleven-spotted lady beetle, eleven-spotted ladybird beetle
Coccinella undecimpunctata, commonly known as the eleven-spot ladybird or eleven-spotted lady beetle, is a small predatory beetle in the family Coccinellidae. It is endemic to the Palearctic region and has been introduced to Australia and New Zealand as a biological control agent. The species is distinguished by eleven black spots on its red or orange elytra, though one central spot creates the appearance of six spots per elytron. It is an effective predator of aphids and is used in integrated pest management programs.
Harmonia dimidiata
Greater Asian Lady Beetle
Harmonia dimidiata is a medium to large predaceous ladybird beetle (7.4–10 mm) native to southern Asia with introduced populations in North America. Adults display reddish-yellow elytra with black markings in a thirteen-spot pattern. The species is a voracious aphid predator with documented prey including Rhopalosiphum maidis, Aphis gossypii, Myzus persicae, and Aphis pomi. Temperature strongly influences its development, fecundity, and predatory capacity, with optimal performance at 24°C. Males produce yellow reflex blood containing harmonine as both chemical defense and nuptial gift during courtship.
Subcoccinella vigintiquatuorpunctata
24-spot Ladybird, Alfalfa Lady Beetle
A small ladybird beetle, 3–4 mm long, with a domed shape and velvety, hair-covered wing-cases. Unlike most ladybirds, it is herbivorous, feeding on fungal mycelium rather than aphids. The species shows high variability in spot patterns, typically bearing 20–24 black spots on a dark orange background, though melanic and spotless forms occur. Winglessness is common, particularly in western populations, with flight ability varying geographically.
