Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 5 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Stiletto

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Common Stiletto

<em>Thereva nobilitata</em>, commonly known as the common stiletto fly, is a medium-sized fly in the family Therevidae, distributed across Europe and parts of western Asia. This species typically inhabits sandy heathlands, coastal dunes, river sandbars, open grasslands, and sparsely vegetated sandy soils where both adults and larvae can exploit loose substrates. Its geographic range extends across much of Europe from the British Isles and Scandinavia south to the Mediterranean, with records extending into parts of North Africa and western Asia. Classified as Least Concern on the IUCN Red List, <em>Thereva nobilitata</em> is among the more frequently encountered therevid flies in European sandy habitats. Adult stiletto flies are predatory, typically hunting small soft-bodied insects on the ground and in low vegetation. The larvae are also predatory, living in soil or sand where they hunt other soil-dwelling invertebrate larvae. Adults are typically grey-bodied with silvery-grey pruinosity and mottled wings, reaching a body length of approximately 10–15 mm. Biological traits such as average lifespan in years, precise body weight, and detailed dietary preferences at the prey species level remain poorly documented for this species. Adults are typically active during warm, sunny weather from late spring through summer.
