Harrison Gray Dyar Jr
Harrison Gray Dyar Jr. (February 14, 1866 – January 21, 1929) was an American entomologist. Dyar's Law, a pattern of geometric progression in the growth of insect parts, is named after him. He was also noted for eccentric pursuits which included digging tunnels under his home. He had a complicated personal life and along with his second wife he adopted the Baháʼí Faith. Early life Dyar was born in Linwood Hill, Rhinebeck, New York, to Harrison Gray Dyar and his wife Eleonora Rosella ().Pamela M.

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lymantriinae
The Lymantriinae (formerly called the Lymantriidae) are a subfamily of moths of the family Erebidae. The taxon was erected by George Hampson in 1893. Many of its component species are referred to as "tussock moths" of one sort or another. The caterpillar, or larval, stage of these species often has a distinctive appearance of alternating bristles and haired projections. Many tussock moth caterpillars have urticating hairs (often hidden among longer, softer hairs), which can cause painful reactions if they come into contact with skin. The subfamily Lymantriinae includes about 350 known genus, genera and over 2,500 known species found in every continent except Antarctica. They are particularly concentrated in sub-Saharan Africa, India, Southeast Asia, and South America. One estimate lists 258 species in Madagascar alone.Schaefer, Paul (1989).

Moth
Moths are a group of insects that includes all members of the order Lepidoptera that are not Butterfly, butterflies. They were previously classified as suborder Heterocera, but the group is Paraphyly, paraphyletic with respect to butterflies (suborder Rhopalocera) and neither subordinate taxon is used in modern classifications. Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although there are also crepuscular and Diurnal animal, diurnal species. Differences between butterflies and moths While the Butterfly, butterflies form a monophyly, monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae a ...
