<span class="mw-page-title-main">Entomology</span> Scientific study of insects

Entomology is the scientific study of insects, a branch of zoology. 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. This wider meaning may still be encountered in informal use.

<span class="mw-page-title-main">Rove beetle</span> Family of beetles

The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is the second largest family in the beetle order, after the true weevils (Curculionidae), which also makes in one of the largest families of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus Leehermania proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems.

The Entomological Society of America (ESA) was founded in 1889 and today has more than 7,000 members, including educators, extension personnel, consultants, students, researchers, and scientists from agricultural departments, health agencies, private industries, colleges and universities, and state and federal governments. It serves the professional and scientific needs of entomologists and people in related disciplines. To facilitate communication among members, the ESA is divided into four sections based on entomological interests, and six branches, based on geographic proximity. The national office is located in Annapolis, Maryland.

<i>Stenus</i> Genus of beetles

Stenus is a genus of semiaquatic rove beetles in the subfamily Steninae, and one of the largest genus in the kingdom Animalia, with some 2700 known species worldwide. They are predators of Collembola and other small arthropods. Adults have a protrusible labium with a sticky tip used in prey capture. To overcome the rapid escape of Collembola, the labium is protruded at high speed by hemolymph pressure, and immediately withdrawn, pulling the prey within the range of the mandibles. However, the labium tip does not easily stick to preys covered in scales or setae or that have a large body size. Stenus comma is more likely to catch such preys by lunging forward and grabbing them directly with its mandibles rather than using its labium. Stenus species are also known for "skimming" on the water surface using their pygidial gland secretions that act as a surfactant and rapidly propel the beetle fast forward, a phenomenon known as the Marangoni effect. Stenus comma has been seen to achieve a velocity of 0.75 m/s, and to cover a distance of up to 15 m if the secretion is continuous.

<span class="mw-page-title-main">Stenusin</span> Chemical compound

Stenusin is a piperidine alkaloid molecule synthesized by rove beetles of the genus Stenus Latreille. By lowering its abdomen and releasing stenusin, this genus of rove beetle are able to quickly escape predators through a process called skimming. Skimming is caused by the low surface tension of stenusin, which rapidly spreads over water surfaces when emitted and allows the beetle to glide away from danger.
