Patchiella
Patchiella is a genus of aphids in the subfamily Pemphiginae, established by Tullgren in 1925. The genus is distinguished by its obligate association with Tilia species, where colonies form distinctive "leaf nests" by folding and binding leaves together. Members exhibit host alternation, migrating between Tilia (primary host) and Araceae (secondary host) seasonally. The genus includes P. kolokasia, recently documented from South Korea, expanding its known range from China and Japan.
Patchiella kolokasia
Patchiella kolokasia is a gall-forming aphid in the subfamily Pemphiginae. It forms distinctive leaf nests on Tilia species and exhibits host alternation, with Araceae serving as secondary hosts. The species was described from China in 1999 and has since been recorded from Japan and, more recently, South Korea. This represents the first documentation of the genus Patchiella on the Korean Peninsula.
