Hoverflies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers ; the adults of many species feed mainly on nectar and pollen , while the larvae ( maggots ) eat a wide range of foods.
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. [1] Another distantly related family of flies, Tephritidae , are true fruit flies because they are frugivorous, and include apple maggot flies and many pests.
Unlike humans, the sex and physical appearance of fruit flies is not influenced by hormones. [16] The appearance and sex of fruit flies is determined only by genetic information. [16] Female fruit flies are substantially larger than male fruit flies, with females having bodies that are up to 30% larger than an adult male. [17] [18]
During the winter, these birds look brown rather than golden and you’ll spot the active little finches clinging to weeds or filling up their stomachs at a bird feeder. 8. Mourning Dove
Like other members of the Drosophilidae, D. suzukii is small, approximately 2 to 3.5 millimetres (5 ⁄ 64 to 9 ⁄ 64 in) in length and 5 to 6.5 millimetres (13 ⁄ 64 to 1 ⁄ 4 in) in wingspan [3] and looks like its fruit and vinegar fly relatives. Its body is yellow to brown with darker bands on the abdomen and it has red eyes.
Drosophila (/ d r ə ˈ s ɒ f ɪ l ə, d r ɒ-, d r oʊ-/ [1] [2]) is a genus of fly, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit.
They include many familiar insects such as house flies, blow flies, mosquitoes, gnats, black flies, midges and fruit flies. More than 150,000 have been formally described and the actual species diversity is much greater, with the flies from many parts of the world yet to be studied intensively.
The glossy pale green ova (eggs) are spherical with a 1-millimetre (0.04 in) diameter. They are said to look like the flower buds of the host plant Galium, and that is where the female lays them. They hatch 6 to 8 days after laying. [6] Up to 200 eggs may be laid by one female, each on a separate plant.
