Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows them to be eaten. Setae on the integument of insects are unicellular, meaning that each is formed from a single epidermal cell of a type called a trichogen, literally meaning "bristle generator". They are at first hollow and in ...
They may be irregular or align in two or more rows. The number of rows, the number of setae in each row, the size and the thickness are significant. In many groups, the acrostical setae are replaced by setulae or hairs. prescutellar (psc) two acrostical bristles, more developed than the other acrosticals, inserted in front of the scutoscutellar ...
Synthetic setae emulate the setae found on the toes of a gecko and scientific research in this area is driven towards the development of dry adhesives. Geckos have no difficulty mastering vertical walls and are apparently capable of adhering themselves to just about any surface.
In most species of bees, the scopa is simply a dense mass of elongated, often branched, hairs (or setae) on the hind leg. When present on the hind legs, the modified hairs are, at a minimum, on the tibia, but some bees also have modified hairs on the femur and/or trochanter.
A general term for a structure by which an object hangs (from Greek language kremastos, meaning "hung up"); for example in entomology: in some Lepidoptera, including most butterflies, the pupa attaches to a surface by the cremaster, a structure at the tip of the pupal abdomen. The cremaster is the homologue of the anal plate of the caterpillar.
These performance features stem from the underlying hierarchical structure which consists of a million microfibrils called setae which further consists of billions of nano-sized branches called spatulae. Mimicking this phenomenon involves four distinct design steps: [19] Making a vertically aligned micro-/nano- fibrillar arrays
Like methadone, Suboxone blocks both the effects of heroin withdrawal and an addict’s craving and, if used properly, does it without causing intoxication. Unlike methadone, it can be prescribed by a certified family physician and taken at home, meaning a recovering addict can lead a normal life, without a daily early-morning commute to a clinic.
the structure of larva and position of primary setae; whether the pupa is exarate or obtect; The morphological characteristics of caterpillars and pupae used for classification are completely different from that of adults; [13]: 637 [14] different classification schemes are sometimes provided separately for classifying adults, larvae, and pupae.
