Cryptorhynchus lapathi is a Eurasian-origin weevil (Curculionidae) introduced to North America, now established as a significant pest of willow (Salix) and poplar (Populus) species. Larvae bore into stems, creating infection courts for pathogens and causing structural weakening that leads to stem breakage. The species has expanded its range considerably in British Columbia since its first detection in 1923, with prevalence linked to thermal regimes—areas with more months above 10°C show higher attack rates. Climate modeling predicts continued northward range expansion and increased suitable habitat area through 2100.

Ctenophora
comb jellies, sea gooseberries, sea walnuts, Venus's girdles
Ctenophora is a phylum of marine invertebrates distinguished by eight rows of fused cilia used for locomotion, called comb rows. They are the largest animals to swim using cilia. Unlike cnidarians, they lack stinging cells and instead capture prey using colloblasts—sticky adhesive cells. The phylum contains approximately 150–186 recognized species exhibiting diverse body plans, from egg-shaped cydippids with retractable tentacles to flattened benthic platyctenids and large-mouthed beroids. Ctenophores possess a decentralized nerve net without a brain, and their phylogenetic position as either the earliest or second-earliest branching animal lineage remains actively debated.

Cydia pomonella
Codling Moth
Cydia pomonella is a tortricid moth and major global pest of apple and pear orchards. The caterpillar, commonly known as the 'worm in the apple,' bores into fruit and prevents normal development, causing premature ripening and crop loss. Adults are attracted to pheromone traps with limited plume reach, requiring multiple traps for reliable monitoring. The species has been detected via environmental DNA in yard waste shipments, highlighting its potential for human-mediated dispersal.

Desidae
intertidal spiders, desid spiders
Desidae is a family of spiders with remarkable ecological diversity, ranging from truly marine intertidal species to inland web-builders. The family was historically defined by intertidal members of the genus Desis, which construct air-filled silk retreats in barnacle shells or kelp holdfasts to survive tidal submersion. Modern circumscription includes inland genera such as Badumna and Phryganoporus. The family contains 63 genera and over 320 species, with the majority native to Australia, New Zealand, and New Caledonia. Some species have become invasive synanthropes, establishing populations in North and South America, Europe, and Asia.

Echidnophaga gallinacea
hen flea, sticktight flea, stickfast flea
Echidnophaga gallinacea is a small, dark brown flea that parasitizes a broad range of bird and mammal hosts including poultry, dogs, cats, and occasionally humans. Adult females embed permanently into host skin—typically on bare areas of the head and face—using a serrated mouthpart to feed on blood, while males remain mobile. Heavy infestations cause ulceration, dermatitis, anemia, and can be fatal to young or small hosts. The species has spread globally through poultry farming and is now established across tropical, subtropical, and temperate regions.

Homalodisca vitripennis
Glassy-winged Sharpshooter
Homalodisca vitripennis, commonly known as the glassy-winged sharpshooter, is a large leafhopper native to the southeastern United States and northeastern Mexico. It has become a major invasive pest in California, Hawaii, and the Pacific Islands, where it vectors Xylella fastidiosa, the bacterium causing Pierce's disease of grapevine—a lethal condition for vineyards. The species exhibits complex vibrational communication during mating, with males and females engaging in duets using species-specific signals. Populations in California's Central Valley have developed significant resistance to neonicotinoid insecticides, particularly imidacloprid, creating challenges for chemical management. Classical biological control using egg parasitoids from the genus Gonatocerus (family Mymaridae) has proven effective, with parasitism rates reaching 80-100% in some areas.
