Hoverfly nectaring on a small flower bud covered with dew drops. Adult syrphid flies are pollinators. Larvae of many hoverfly species prey upon pest insects, including aphids and leafhoppers, which spread some diseases such as curly top, so they are seen in biocontrol as a natural means of reducing levels
This species appears as a shield beetle, with an orange bottom, a big black stripe, a black joiner with two white quarter ovals and a small white oval. the head is round and the antennae are black with yellow tips. [3]
Fairyflies are very tiny insects, like most chalcidoid wasps, mostly ranging from 0.5 to 1.0 mm (0.020 to 0.039 in) long. They include the world's smallest known insect, with a body length of only 0.139 mm (0.0055 in), and the smallest known flying insect, only 0.15 mm (0.0059 in) long. They usually have nonmetallic black, brown, or yellow bodies.
Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
The thorax has yellow sides separated by a bold black panel in which are three yellow spots, resembling a highland darter (Sympetrum nigrescens). [3] The male has a mainly black thorax and abdomen. The abdomen has small yellow marks on the side, that darken with age. The wings are clear. [3] The female has black legs and brown eyes.
Bombus ternarius, commonly known as the orange-belted bumblebee or tricolored bumblebee, [2] is a yellow, orange and black bumblebee.It is a ground-nesting social insect whose colony cycle lasts only one season, common throughout the northeastern United States and much of Canada. [3]
It reaches 9–18 millimetres (0.35–0.71 in) in length. It features prominent yellow and black patterns along its head and abdomen, in what is believed to be an evolutionary attempt to mimic wasps and avoid predation. It also possesses thin legs and antennae that move in small, quick movements, which supports the wasp-mimicking hypothesis.
Adult yellow flies are around 1 centimetre (0.39 in) long with yellow bodies, mid-legs, and hind-legs, and black fore-legs. The eyes are blue-green with purple bands. They fly with little sound, and the first sign of their presence noticed by humans is usually their bite. [4]
