Coarse Stained-glass Leafhopper

Argaterma alticola, the coarse stained-glass leafhopper, is a critically endangered hemipteran insect in the family Cicadellidae, known only from a highly restricted distribution in Azerbaijan. Leafhoppers in this family are small, typically fast-moving plant-feeding insects that suck phloem sap from their host plants and can be economically significant in agricultural contexts. Argaterma alticola is associated with montane or high-altitude grassland or scrub vegetation in the Caucasus region, where its highly localized range makes it exceptionally vulnerable to habitat alteration. The Critically Endangered assessment reflects the tiny known range, presumed small population size, and threats from overgrazing, agricultural intensification, and climate-driven vegetation shifts in the Caucasus mountain systems. The family Cicadellidae is among the most species-rich families of insects globally, with over 20,000 described species, but many specialized species with restricted ranges remain poorly studied and face extinction before they can be formally surveyed. Conservation of this species depends on identifying and protecting the specific grassland habitats in Azerbaijan where it persists and understanding its host plant associations and population size.

호주 동부와 동남부의 상징적인 유대류로, 체중이 최대 15kg이며 저칼로리인 유칼립투스 잎 식단에서 에너지를 절약하기 위해 하루 최대 22시간을 잠으로 보낸다. 대부분의 다른 포유류를 죽일 수 있는 유독한 유칼립투스 성분을 처리하도록 고도로 특화되어, 해독에 특별히 적응된 장내 미생물총을 지닌다. 2022년 기후 변화, 서식지 개발, 클라미디아 감염으로 인한 개체수 감소로 위기종으로 지정되었다.
