Chopard's Cave-cricket

Chopard's Cave Cricket (Dolichopoda chopardi) is a camel cricket or cave cricket in the family Rhaphidophoridae, found in cave systems and subterranean environments of the western Mediterranean region, including areas of southern France, northern Italy, and possibly adjacent territories. Cave crickets of the genus Dolichopoda are obligate or near-obligate cave dwellers (troglobionts or troglophiles), characterised by their extreme leg elongation — particularly the hind legs and antennae, which are several times longer than the body — reduced eyes or eyelessness, lack of wings, and depigmented or pale yellowish-brown body colouration. These adaptations reflect evolutionary response to permanent cave darkness. Dolichopoda cave crickets feed as omnivores on organic detritus, bat guano, fungi, and invertebrates carried into cave systems by water or wind. They are sensitive bio-indicators of cave ecosystem health. The species is named in honour of Lucien Chopard, a French entomologist. The IUCN classifies this species as Data Deficient, reflecting limited survey data on its distribution and population status across cave systems within its range. Cave-dwelling invertebrates face threats from groundwater pollution, cave tourism impacts, changes in cave hydrology, and the spread of white-nose syndrome affecting bat populations whose guano provides food resources.

Long-tailed Sylph

One of the most strikingly ornamented hummingbirds, male long-tailed sylphs have iridescent green plumage and dramatically elongated, ribbon-like outer tail feathers reaching up to 22 cm — over three times the body length. Found in Andean cloud forests of Colombia and Venezuela, they inhabit humid montane forest between 1,400–2,800 meters elevation. Males perform elaborate display flights to attract females. Their extravagant tails are a classic example of sexual selection via female preference.
