The Small catchy or dwarf earworm ( labia minor , Syn : Forficula minor ; English Lesser earwig or small earwig ) is a kind of catchy tunes . It is distributed worldwide in temperate climates and prefers warm locations such as compost heaps in the colder parts of its range. It is chocolate brown and 4–7 mm long including the grasping forceps .
description
The small earwig is 4 to 7 millimeters long and therefore about half the size of the common earwig ( Forficula auricularia ). It's chocolate brown and less shiny than the chestnut common catchy tune. The whole body is covered with fine yellow bristle hairs called setae . The feelers are lighter in color. The grasping forceps ( cercus ) on the animal's abdomen help unfold the wings in preparation for flight. In contrast to the common earwig, the lesser earwig often flies.
ecology
The earwig feeds on rotting plant material and other residues. In cooler climates, it occurs only in warm places, such as B. on compost heaps. It is most commonly encountered when moving the compost. What is unusual for an insect is the maternal care of the eggs and offspring, with the mother feeding them for one to two weeks after hatching.
distribution
The earwig is widespread in temperate zones around the world, including Germany and large parts of Europe. It is unclear whether it is a native species or a historically introduced species in North America. The first documentation from the United States is from 1838, but the species may have been present long before that. Its occurrence in British Columbia and Quebec extends further north than that of any other catchy species; it is the only known catchy species in Quebec.
The earwig was also introduced as a neozoon in Australia , Madeira , the Galapagos Islands and the Philippines . However, the species is likely to be frequently overlooked due to its small size and may be more common than is currently known.
Taxonomy
The catchy tune was first described by Carl von Linné in the 10th edition of his work Systema Naturae in 1758 and named with the name Forficula minor . When William Elford Leach established the genus Labia in 1815 , Linnaeus' Forficula minor was renamed to the type species of this new genus and Labia minor . Synonyms are Forficula livida ( Gmelin , 1788), Forficula media ( Marsh. , 1802) and Labia minuta ( Scudder , 1862).
