The compound eyes are simpler in structure than those of other arthropods, with the individual ommatidia not being arranged in a compact pattern. They can probably detect movement, but are unlikely to be able to form a true image. In front of the ocelli is an additional organ that probably functions as a chemoreceptor. [10]
[5] Around half of all mayfly species whose reproductive biology has been described are parthenogenetic (able to asexually reproduce), including both partially and exclusively parthenogenetic populations and species. [18] Many species breed in moving water, where there is a tendency for the eggs and nymphs to get washed downstream.
The largest is the dobsonfly Acanthacorydalis fruhstorferi, which can have a wingspan of up to 21.6 cm (8.5 in), making it the largest aquatic insect in the world by this measurement. [38] This species is native to China and Vietnam, and its body can be up to 10.5 cm (4.1 in) long. [39]
Millipedes (originating from the Latin mille, "thousand", and pes, "foot") [1] [2] 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.
The infraorder name Isoptera is derived from the Greek words iso (equal) and ptera (winged), which refers to the nearly equal size of the fore and hind wings. [15] " Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes.
Brachiopod fossils show great diversity in the morphology of the shells and lophophore, while the modern genera show less diversity but provide soft-bodied characteristics. Both fossils and extant species have limitations that make it difficult to produce a comprehensive classification of brachiopods based on morphology.
Bast fibers are collected from the outer cell layers of the plant's stem. These fibers are used for durable yarn, fabric, packaging, and paper. Some examples are flax, jute, kenaf, industrial hemp, ramie, rattan, and vine fibers. [9] A field of jute Fruit fiber: Fibers collected from the fruit of the plant, for example, coconut fiber .
Additional evidence emerged when F. A. McKittrick (1965) noted similar morphological characteristics between some termites and cockroach nymphs. [18] The similarities among these cockroaches and termites have led some scientists to reclassify termites as a single family, the Termitidae , within the order Blattodea.
