This glossary of entomology describes terms used in the formal study of insect species by entomologists.. When present, elytra of the Staphylinidae are markedly abbreviate. This fly in the genus Scaptomyza has clearly visible rows of para-sagittal acrostichal bristles on its thorax the alitrunk of aculeate Hymenoptera comprises the three thoracic segments, plus the propodeum, which strictly ...
Male Banded demoiselle. The banded demoiselle (Calopteryx splendens) is a species of damselfly belonging to the family Calopterygidae. [1] [3] It is often found along slow-flowing streams and rivers.
Beautiful demoiselles live mainly near small to medium-sized streams and creeks. [7] They prefer a relatively low water temperature and a moderate to fast flow. The water must not be nutrient-rich . In the northern part of their range, such as in Norway and Finland, they are also found near medium-sized rivers or even larger streams.
Those who study entomology are known as entomologists. In the past, the term insect was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arachnids, myriapods, and crustaceans. The field is also referred to as insectology in American English, while in British ...
Calopterygidae is a family of damselflies, in the suborder Zygoptera. [2] They are commonly known as the broad-winged damselflies, [3] demoiselles, or jewelwings. [4] These rather large damselflies have wingspans of 50–80 mm (compared to about 44 mm in the common bluetail damselfly, Ischnura elegans), are often metallic-coloured, and can be differentiated from other damselflies by the ...
Researchers from The Institute of Cancer Research in London have developed a new test that can predict colorectal cancer risk in people with IBD with more than 90% accuracy.
The chasers, darters, skimmers, and perchers and their relatives form the Libellulidae, the largest family of dragonflies. [2] It is sometimes considered to contain the Corduliidae as the subfamily Corduliinae and the Macromiidae as the subfamily Macromiinae. Even if these are excluded (as Silsby does), there remains a family of over 1000 species.
As many as 3.1 million Americans have IBD, an umbrella-term form conditions — primarily Crohn’s disease and ulcerative colitis — in which inflammation of the bowel produces various unwelcome ...
