Summary
[edit]DescriptionMetapterus (29203697513).jpg |
The Reduviidae (i.e., assassin bugs), large cosmopolitan family, almost all are terrestrial ambush predators, about 7000 species have been described They are stalking, predatory insects that can be collected on palm fronds, cliffs, spider webbing, or near lights at night (many can be collected by blacklight). Adult insects range from about 4.0 to 40 mm, depending on the species. They most commonly have an elongated head with a distinct narrowed 'neck', long legs, and prominent, segmented, tubular mouthparts, most commonly called the proboscis, but some authors use the term "rostrum". Many species can deliver a painful stab with the proboscis, injecting venom or digestive juices. They feed mainly on insects, some tropical species feed on the blood of warm-blooded animals and human and (represent a transition from predators to parasites). The Emesinae, or thread-legged bugs , are conspicuously different from the other reduviids by their very slender body form. They walk on their mid and hind legs; the front pair is raptorial. Семейство Хищнецы (Reduviidae) - это так называемые assassin bugs - жуки-убийцы, представители которого широко распространены по всему миру, описано их около 7000 видов. Хищнецы активны преимущественно ночью, (многие из них могут собираться при ультрафиолетовом или инфракрасном излучении, невидимом глазу). Днем прячутся в траве, на деревьях, в укрытиях. Активные хищники, они питаются преимущественно насекомыми, ряд тропических видов питается и кровью теплокровных животных и человека (представляют переход от хищников к паразитам). Взрослые насекомые имеют размер приблизительно от 4,0 до 40 мм, в зависимости от вида, чаще всего имеют удлиненную голову с ярко выраженной суженной "шеей", длинные ноги, и видающийся вперед сегментный, трубчатый рот, чаще называемый хобот, но некоторые авторы используют термин rostrum - клюв. Многие виды могут нанести хоботком болезненный удар, впрыскивая яд или пищеварительный сок. Подсемейство Emesinae заметно отличается от других подсемейств очень стройной формой тела. Они ходят на средних и задних ногах; передняя пара ног - хищные. |
