Clifton's Anguloa

Clifton's Anguloa, Anguloa cliftonii, is a striking terrestrial orchid in the family Orchidaceae native to the cloud forests of the Andes in Colombia, Ecuador, and Peru. The genus Anguloa, known as cradle orchids or tulip orchids, is celebrated among orchid enthusiasts for its large, tulip-shaped, waxy flowers that rock gently when moved, simulating the movement of a bee—a presumed pollination adaptation. The flowers of Anguloa cliftonii are creamy white to pale yellow, often with pink or rose spotting, and are produced singly on erect peduncles arising from the base of large, pleated pseudobulbs. The plant is a cool-growing epiphyte or lithophyte found in humid montane forest at elevations between approximately 1,500 and 2,500 meters in the Andes. Anguloa species are pollinated by male euglossine bees attracted to fragrant compounds. The cloud forest habitats of the Andes are among the world's most biodiverse ecosystems and simultaneously among the most threatened, subject to deforestation for agriculture, cattle ranching, and coca cultivation. Many Andean orchid species are also threatened by over-collection for the horticultural trade. Anguloa cliftonii is cultivated in specialist collections and is the subject of conservation concern in its native range.

Cobweb weaver

The noble false widow (Steatoda nobilis) is a theridiid spider that has attracted considerable media attention in the British Isles and along the Atlantic coast of Europe due to its painful but rarely dangerous bite and its rapid range expansion facilitated by human activity. Originally native to the Canary Islands and Madeira, the species arrived in southern England during the 19th century, likely via banana shipments, and has since spread northward through Britain and westward into Ireland, while also establishing populations along the Iberian Peninsula and Atlantic France. Females are robust, with a dark brown carapace and a distinctive cream-colored pattern on the bulbous abdomen that varies between individuals; females reach 8.5–14 millimeters in body length, making this one of the larger European theridiids. The species constructs persistent, tangled cobwebs in sheltered locations outside buildings—under window ledges, in door frames, and in garden walls—as well as within homes in cooler seasons. It is a generalist predator, capturing insects and other invertebrates, and has been reported to occasionally subdue prey considerably larger than itself, including small lizards. Steatoda nobilis venom produces steatodism, which can cause localized pain, swelling, and in rare cases systemic symptoms. Its conservation status has not been formally assessed, but its expanding range demonstrates considerable resilience.
