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.

Comet Darner

<em>Anax longipes</em>, the comet darner, is a large dragonfly in the family Aeshnidae, assessed as Least Concern on the IUCN Red List. It is endemic to the United States, where it inhabits lakes, ponds, and slow-moving rivers with clear water and abundant emergent vegetation. The comet darner is one of the largest North American dragonflies and is distinguished by its brilliant coloration, including a green thorax and a red-spotted abdomen in mature males. The species name longipes refers to its notably long legs. Adults are powerful aerial predators, feeding on a variety of flying insects captured in flight. Larvae are aquatic and predatory, developing in the benthic zone of freshwater habitats where they feed on invertebrates and small vertebrates. The comet darner undertakes seasonal dispersal movements and is most commonly observed near its breeding water bodies during the warmer months.
