The moult takes place in two stages; [35] the back half is lost first, followed two or three days later by the front. This method of moulting is different from that of most arthropods, which shed their cuticle in a single process. It is theorized that this allows woodlice to maintain partial mobility while molting.
Louse (pl.: lice) is the common name for any member of the clade Phthiraptera, which contains nearly 5,000 species of wingless parasitic insects. Phthiraptera has variously been recognized as an order, infraorder, or a parvorder, as a result of developments in phylogenetic research. [1] [2] [3]
Argulus foliaceus. Argulus foliaceus, also known as the common fish louse, is a species of fish lice in the family Argulidae. [1] It is "the most common and widespread native argulid in the Palaearctic" [2] and "one of the most widespread crustacean ectoparasites of freshwater fish in the world", considering its distribution and range of hosts.

[3] In older literature, this group is often referred to as the Pupipara (" pupa -bearers"), because, unlike virtually all other insects, most of the larval development takes place inside the mother's body, and pupation occurs almost immediately after "birth" – in essence, instead of laying eggs, a female lays full-sized pupae one at a time.
The lobster louse was first reported in 1826 by Audoin & Milne-Edwards. [2] N. astaci has been found on lobsters inhabiting locations including Scotland, [3] Lundy Island in the Bristol Channel [4] and as far south as France and Portugal. [5] The louse possesses a narrow suctorial mouthpart to feed on host haemolymph.
On July 25, 1978, the world's first "test tube baby" was born. Louise Brown was the first person conceived through in vitro fertilization (IVF) and her birth eventually led to one of her doctors ...
Strigiphilus garylarsoni is a species of chewing louse found only on owls. The species was first described by biologist Dale H. Clayton in 1990, who named it after cartoonist Gary Larson. Its type host is the Northern white-faced owl (Ptilopsis leucotis). [1] The type location is Ndola, Zambia. [1]
Acyrthosiphon pisum, commonly known as the pea aphid (and colloquially known as the green dolphin, [1] [2] pea louse, and clover louse [3]), is a sap-sucking insect in the family Aphididae. It feeds on several species of legumes (plant family Fabaceae ) worldwide, including forage crops, such as pea , clover , alfalfa , and broad bean , [ 4 ...
