Trachysphaera lobata, also known as the sand pill millipede, [1] is a species of pill millipede within the genus Trachysphaera and family Glomeridae. [2]
Trachysphaera lobata is a small pill millipede species which can roll into a ball of up to 3 mm in diameter. [3] Each body segments posterior margin has a raised ridge which is adorned with rows of tubercles. [3] T. lobata has been recorded to reach lengths up to 4.1 mm long and a width of 1.9 mm wide. [4] Individuals possess 17 pairs of legs. [4] Eyes consist of a row of 4 or 5 ocelli. [3] Young T. lobata are white, however adult are brown in colour. [4]
Trachysphaera lobata is present within the United Kingdom where populations exist in Cornwall, the Isle of Wight and South Wales. [5] It can also be found in France [5] where populations have been found in the western side of the country. [3]
Trachysphaera lobata can be found in woodlands inside soil, leaf litter and dead wood. [3] Preferred soils are sandy and humus rich where the millipede can be found at depths of 15 cm. [3] In France T. lobata is found in a variety of calcareous sites ranging from woodlands, caves and quarries. [3]
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of Eumillipes persephone, which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures.
Myriapods are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial.
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs or roly polies. Other common names include slaters,potato bugs, butchy boys and doodle bugs. Most species are native to the Mediterranean Basin, while a few species have wider European distributions. The best-known species, Armadillidium vulgare, was introduced to New England in the early 19th century and has become widespread throughout North America.
Pill millipedes are any members of two living orders of millipedes, often grouped together into a single superorder, Oniscomorpha. The name Oniscomorpha refers to the millipedes' resemblance to certain woodlice (Oniscidea), also called pillbugs or "roly-polies". However, millipedes and woodlice are not closely related ; rather, this is a case of convergent evolution.
Glomeris marginata is a common European species of pill millipede. It is a short millipede, rounded in cross-section, which is capable of rolling itself up into a ball ("volvation") when disturbed. This behaviour is also found in the pill woodlouse Armadillidium, with which G. marginata is often confused.
Rhamnus cathartica, the European buckthorn, common buckthorn, purging buckthorn, or just buckthorn, is a species of small tree in the flowering plant family Rhamnaceae. It is native to Europe, northwest Africa and western Asia, from the central British Isles south to Morocco, and east to Kyrgyzstan. It was introduced to North America as an ornamental shrub in the early 19th century or perhaps before, and is now naturalized in the northern half of the continent, and is classified as an invasive plant in several US states and in Ontario, Canada.
A woodlouse is any crustacean belonging to the suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood, and from louse, a parasitic insect, although woodlice are not insects.
The Wilderness is a Site of Special Scientific Interest which is located on the Isle of Wight, England. It is close to the village of Rookley in the valley of the River Medina. The Wilderness is an area of wet woodland over a quite deep peat soil with adjacent areas of unimproved acid grassland and wet grassland. The SSSI covers an area of 12.59 hectares, the boundaries being reset in 1984 to exclude an area of grassland which had been artificially improved.
Eucalyptus salmonophloia, commonly known as salmon gum, wurak or weerluk or woonert or marrlinja. is a species of small to medium-sized tree that is endemic to Western Australia. It has smooth bark, narrow lance-shaped to curved adult leaves, flower buds in groups of between nine and thirteen, creamy white flowers and hemispherical fruit.
Sphaerotheriida is an order of millipedes in the infraclass Pentazonia, sometimes known as giant pill millipedes. They inhabit Southern Africa, Madagascar, South and Southeast Asia, Australia and New Zealand. Like the Northern Hemisphere pill millipedes of the order Glomerida, these millipedes can roll into a ball when disturbed. When they are rolled-up, most sphaerotheriidans reach a maximum size of a cherry or golf ball, but some species from Madagascar can even reach the size of an orange. When rolled-up, predators are unable to unravel giant pill millipedes since the margins of their second and last dorsal plates fit perfectly into one another, creating a sealed ball. A few giant pill millipede species are able to produce sound, the only millipedes known to do this. This order of millipedes is also unique in that some African species are used for medicinal purposes.
Sphaeromimus, or the chirping giant pill millipedes, is a genus of giant pill millipedes endemic to southeastern Madagascar. Though described in 1902, the genus was up to 2005 known from a single male specimen, whose appearance was so unusual that the authors suspected a mislabeled giant pill-millipede from India. Their unusual and distinct morphology includes well-developed stridulation organs, probably as devices for courtship. These are the male ‘harp’ and the female ‘washboard’, which contain more stridulation ribs than in other members of the order Sphaerotheriida. They have a closer affinity with the Indian genus Arthrosphaera than to other Malagasy genera, though all belong to the Arthrosphaeridae.
Trachysphaera is a genus of dwarf pill millipedes in the order Glomerida. Just over 30 species are known, making it the third most species-rich genus of Glomerida. Trachysphaera species are patchily distributed throughout Europe and western Asia, extending from Spain to Caucasia. Members of this genus are tiny, with modified appearances resembling that of calcareous stones.
Zoosphaerium neptunus, also known as the giant emerald pill millipede, is a species of millipede within the family Arthrosphaeridae. It is an example of island gigantism, being the largest known pill-millipede in the world, with some individuals reaching a maximum length of 90 mm long. The species is endemic to Madagascar, where it is known to swarm at certain times of the year. Z. neptunus is the only known species within the order Sphaerotheriida that is known to exhibit this mass swarming behaviour.
Geoglomeris is a genus of millipedes belonging to the family Glomeridae.
Opisthocheiridae is a family of millipedes belonging to the order Chordeumatida. These millipedes range from 5 mm to 16 mm in length and are found from Belgium to Morocco. Adult millipedes in this family have 26 or 30 segments. This family includes the cave-dwelling species Opisthocheiron canayerensis, notable as one of few chordeumatidan species with only 26 segments. The adult female of this species has only 42 pairs of legs, and the adult male has only 40 leg pairs, as one would expect for adult chordeumatidans with four fewer segments than typically found in this order.
Zoosphaerium darthvaderi, also known as the Darth Vader giant pill millipede, is a species of giant pill millipede endemic to the island state of Madagascar. It is named after the Star Wars character Darth Vader. The millipede is restricted to the Ambohitantely Reserve and is considered an extremely endangered species.
Atrichum tenellum, also known as the slender smoothcap, is a species of moss belonging to the family Polytrichaceae. It is red listed in Iceland as a critically endangered (CR) species. In Iceland, it is only found in two geothermal areas.
Polyzonium germanicum, also known as the Kentish pinhead or boring millipede is a species of millipede within the family Polyzoniidae.
Analavelona, also known as Analavelona Massif, is a mountain in southwestern Madagascar. The massif is home to an enclave of montane subhumid forest, which is considered a sacred forest by the local people and notable for its biodiversity.
