Perlidae P1400217a
The Perlidae are a family of stoneflies, with more than 50 genera and 1,100 described species. The majority of the Perlidae are found in eastern North America, but they occur worldwide except for Antarctica and parts of Africa. Their lifecycles range between one and three years. They adults emerge in the summer; they are very active and known to be attracted to light sources. They are usually very sensitive to changes in environment. Perlidae are usually lotic and lentic erosional. They are found in cool, clear medium-sized to large streams and sometimes in larger, warm rivers that carry silt. They are crawlers and can move quickly. In still water, no water moves over their gills, so they move their bodies up and down to keep oxygen flowing over them. They are engulfer-predators. They consume all types of invertebrates Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), de ...

Brahmana (stonefly)
The Brahmanas (; Sanskrit: , ''Brāhmaṇam'') are Vedic śruti works attached to the Samhitas (hymns and mantras) of the Rig, Sama, Yajur, and Atharva Vedas. They are a secondary layer or classification of Sanskrit texts embedded within each Veda, which explain and instruct on the performance of Vedic rituals (in which the related Samhitas are recited). In addition to explaining the symbolism and meaning of the Samhitas, Brahmana literature also expounds scientific knowledge of the Vedic Period, including observational astronomy and, particularly in relation to altar construction, geometry. Divergent in nature, some Brahmanas also contain mystical and philosophical material that constitutes Aranyakas and Upanishads. Each Veda has one or more of its own Brahmanas, and each Brahmana is generally associated with a particular Shakha or Vedic school. Less than twenty Brahmanas are currently extant, as most have been lost or destroyed. Dating of the final codification of the ''B ...
