Habitat & Geographic Range

Cheetah

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 9 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Red-legged Robberfly

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Cheetah

The fastest land animal on Earth, reaching speeds of 112 km/h over short distances across African and Iranian grasslands. Slender build with a deep chest, long legs, and distinctive black tear-stripe markings. Unlike other big cats, cheetahs vocalize with chirps and purrs. Vulnerable, with only ~7,000 remaining due to habitat fragmentation and competition with larger predators.

Common Red-legged Robberfly

<em>Dioctria rufipes</em>, the common red-legged robberfly, is a predatory fly in the family Asilidae, order Diptera. It is distributed across northwestern Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden, typically favoring woodland edges, hedgerows, and meadows with abundant vegetation. The species is assessed as Least Concern on the IUCN Red List, reflecting stable populations across its European range. Robberflies in the genus Dioctria are slender, elongated flies characterized by a distinctive long proboscis used to inject paralyzing saliva into prey. <em>Dioctria rufipes</em> typically hunts smaller flying insects, including midges, small flies, and other soft-bodied arthropods, ambushing prey from resting perches on vegetation and capturing it mid-flight. Adults are typically active from late spring to early autumn, coinciding with peak insect activity. The red or reddish-orange coloration of the hind femora is the diagnostic feature that gives this species its common name. Larvae develop in soil or decaying wood, where they are believed to be predatory on other invertebrate larvae. Biological traits such as precise lifespan, body measurements, and diet composition remain poorly documented in quantitative studies. The species is considered an important component of invertebrate predator guilds in European agricultural landscapes.
