Pupa of the rose chafer beetle, Cetonia aurata Tumbler (pupa) of a mosquito. Unlike most pupae, tumblers can swim around actively. A pupa (from Latin pupa 'doll'; pl.: pupae) is the life stage of some insects undergoing transformation between immature and mature stages.
The wings, head parts of thorax, and abdomen of Lepidoptera are covered with minute scales, from which feature the order Lepidoptera derives its names, the word lepidos in Ancient Greek meaning "scale". Most scales are lamellar (blade like) and attached with a pedicel, while other forms may be hair like or specialised as secondary sexual ...
A newborn is, in colloquial use, a baby who is only hours, days, or weeks old; while in medical contexts, a newborn or neonate (from Latin, neonatus, newborn) is an infant in the first 28 days after birth [2] (the term applies to premature, full term, and postmature infants).
Another example is the blue wildebeest, the calves of which can stand within an average of six minutes from birth and walk within thirty minutes; [5] [6] they can outrun a hyena within a day. [ 7 ] [ 8 ] [ 9 ] Such behavior gives them an advantage over other herbivore species and they are 100 times more abundant in the Serengeti ecosystem than ...
[5] The thorax consists of three segments – the hindmost two, the mesothorax and metathorax, being fused. Each segment bears a pair of legs which usually terminate in a single claw. The legs are robust and often clad in bristles, hairs or spines. Wing pads develop on the mesothorax, and in some species, hindwing pads develop on the metathorax ...
The insect body is divided into three parts: the head, thorax, and abdomen. [2] The head is specialized for sensory input and food intake; the thorax, which is the anchor point for the legs and wings (if present), is specialized for locomotion; and the abdomen is for digestion , respiration , excretion , and reproduction.
The presence of PG usually indicates fetal lung maturity. For the S/A ratio, the result is given as milligrams of surfactant per gram of protein. A S/A ratio less than 35 indicates immature lungs, between 35 and 55 is indeterminate, and greater than 55 indicates mature surfactant production (correlating with an L/S ratio of 2.2 or greater).
The average number of young found in nests is 2.5, and the average number that fledge is about 1.5, due to the occasional production of infertile eggs and various natural losses of nestlings. [11] [58] [63] After hatching, the chicks (called "eyases" [95]) are covered with creamy-white down and have disproportionately large feet. [88]
