Habitat & Geographic Range

藍鯨

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common sawfly

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found across Europe (7 countries) and North America (Canada, United States).

藍鯨

蓝鲸是地球上已知存在过的最大动物，体长可达33米，体重达200吨，其心脏单独就重达一辆小型轿车的重量。分布于各大洋，在极地觅食地和热带繁殖地之间进行迁徙。它们是滤食性动物，每日可消耗多达4吨磷虾。蓝鲸被列为濒危物种，20世纪捕鲸活动使其濒临灭绝，目前全球种群估计约为1万至2.5万头。

Common sawfly

<em>Hoplocampa brevis</em>, the plum sawfly or common sawfly, is a hymenopteran insect in the family Tenthredinidae. The species is distributed across Europe and has been introduced to parts of North America, with records from Canada and the United States, typically in association with commercial plum and cherry orchards. Adults are small, wasp-like insects approximately 4–5 millimeters in length, with pale yellow-brown coloration. Females lay eggs inside flower buds of <em>Prunus</em> species during blossoming, and the hatching larvae burrow into developing fruitlets, feeding on the contents before exiting to pupate in the soil. Larval feeding causes fruitlets to drop prematurely, and infestations can cause economically significant losses in plum and damson production. The species is not currently evaluated on the IUCN Red List. Adults feed on nectar and pollen, and the species typically produces one generation per year, with adults emerging in spring coinciding with the blossoming period of host trees. The larvae are creamy white with a brownish head capsule and produce a distinctive, unpleasant odor when disturbed. Biological traits such as average lifespan, body weight, and detailed non-larval dietary composition remain poorly documented in standardized ecological databases.
