Campylomma
mullein bugs
Campylomma is a genus of plant bugs (family Miridae, tribe Nasocorini) comprising at least 12 recognized species. The genus is best known from detailed studies of C. verbasci, the mullein bug, which exhibits a predator-phytophage feeding strategy and has been investigated for pheromone-based mating disruption in orchard systems. Japanese species have been taxonomically revised, with emphasis on genitalic characters for identification. The genus occurs across temperate regions of the Northern Hemisphere including North America, Europe, and East Asia.

Chaetocnema confinis
sweetpotato flea beetle
Chaetocnema confinis is a small flea beetle (Chrysomelidae: Alticinae) with a cosmopolitan distribution spanning Africa, the Caribbean, Central and North America, South America, Oceania, and Southern Asia. It is a significant agricultural pest of sweetpotato (Ipomoea batatas), with adults feeding on foliage and larvae developing in soil to feed on tuberous roots. Larval feeding causes distinctive linear epidermal damage to storage roots, creating economic losses in commercial production. The species has been studied intensively in Japan, where seasonal damage patterns have been documented.

Coptotermes
Coptotermes is a genus of subterranean termites in the family Rhinotermitidae, containing approximately 71 described species. The genus is thought to have originated in Southeast Asia and includes some of the world's most economically destructive termite pests, notably Coptotermes formosanus (Formosan subterranean termite) and C. gestroi (Asian subterranean termite). A 2013 consensus among 31 termite experts reduced the number of validated species from 69 to 21 based on morphological and molecular evidence, with many historical names suspected to be synonyms. Species in this genus exhibit complex social behaviors including age-based task division and unique nitrogen recycling strategies.

Periplaneta japonica
Japanese cockroach, Yamato cockroach
Periplaneta japonica is a cold-tolerant cockroach native to Japan, adapted to cooler northern climates. It possesses a flexible life cycle with facultative nymphal diapause, allowing nymphs to overwinter once or twice before reaching maturity. The species produces a unique viscous proteinaceous secretion in nymphs that enables active defense against ant predators. First documented in the United States in 2012 in New York City, it has been observed to survive outdoors in freezing temperatures, distinguishing it from most urban cockroach pests.

Platnickina mneon
A comb-footed spider in the family Theridiidae, originally described from a female specimen collected in Saga Prefecture, Kyushu, Japan in 1906. The species was recently reinstated as valid based on distinct body coloration, markings, genital morphology, and molecular data (partial mitochondrial COI gene), having been previously synonymized with Yunohamella lyrica. Molecular analysis revealed that females previously identified as Platnickina mneon are conspecific with males associated with Yunohamella varietas, leading to the latter's synonymization. The species is currently classified under the genus Platnickina, though it was transferred to Yunohamella in the revision that reestablished its validity.

Prociphilus
Woolly Aphids
Prociphilus is a genus of woolly aphids in the family Aphididae, subfamily Eriosomatinae, comprising approximately 50 species. These aphids are notable for inducing gall formation on host plants, within which they reside and feed. The genus exhibits complex life cycles including host alternation and polyphenism, with multiple distinct morphs adapted to different hosts and conditions. Several species have documented mutualistic relationships with ants, and some display remarkable seasonal phenomena such as the mass emergence of Prociphilus oriens in Japan, which is culturally associated with the first snowfall.

Pseudoedophrys hilleri
Peach Root Weevil
Pseudoedophrys hilleri is a species of broad-nosed weevil in the family Curculionidae. Native to Japan, it has been introduced to eastern North America and is now established in multiple U.S. states and the District of Columbia. It is the sole described species in its genus. The common name "Peach Root Weevil" suggests association with peach cultivation, though specific host relationships require verification.

Pseudostenophylax
northern caddisflies
Pseudostenophylax is a genus of northern caddisflies in the family Limnephilidae, containing at least 80 described species. The genus was established by Martynov in 1909 with Pseudostenophylax fumosus as the type species. Species are primarily distributed across northern regions of North America and Eurasia, with notable diversity in Japan and alpine regions. Research on Japanese species has revealed strong phylogeographic patterns linked to mountain formation and glacial history.

Pterallastes
Pterallastes is a genus of bee-mimicking hoverflies (family Syrphidae) described by Loew in 1863. The genus contains four recognized species with a disjunct distribution: one species in North America (P. thoracicus), one in Japan (P. unicolor), and two in China (P. bomboides, P. bettyae). These flies exhibit Batesian mimicry of bees, a common defensive strategy in the subfamily Eristalinae.
