Life cycle of stable fly Stomoxys calcitrans, showing eggs, 3 larval instars, pupa, and adult. Some other anatomical distinction exists between the larvae of the Nematocera and the Brachycera. Especially in the Brachycera, little demarcation is seen between the thorax and abdomen, though the demarcation may be visible in many Nematocera, such ...
Emily Dickinson's 1855 poem "I Heard a Fly Buzz When I Died" speaks of flies in the context of death. [76] In William Golding's 1954 novel Lord of the Flies, the fly is, however, a symbol of the children involved. [77] Ogden Nash's humorous two-line 1942 poem "God in His wisdom made the fly/And then forgot to tell us why." indicates the debate ...
A newly emerged fly has many golden hairs on its thorax which may be lost throughout the life of the fly. The stripes on the thorax are not as prominent as on the house fly and the tips of the wings overlap when at rest. [9] The cluster fly is slightly larger than a house fly at 9.525-12.7mm (3/8-1/2 inch) long. [16]
The fly Megaselia scalaris (often called the laboratory fly) is a member of the order Diptera and the family Phoridae, and it is widely distributed in warm regions of the world. The family members are commonly known as the "humpbacked fly", the "coffin fly", and the "scuttle fly". [ 2 ]
Their life cycle is broken down into four stages: embryo, larva, pupa, adult. [30] The eggs, which are about 0.5 mm long, hatch after 12–15 hours (at 25 °C or 77 °F). [ 25 ] [ 26 ] The resulting larvae grow for about four days (at 25 °C) while molting twice (into second- and third-instar larvae), at about 24 and 48 hours after hatching.
The life cycle and development of Phormia regina is similar to that of most other Dipteran species, in which females oviposit their eggs onto a nutrient substrate. Then, after hatching, the larvae feed throughout three instar stages until they have stored up enough calories to commence pupation and finally emerge as adult blow flies.
Tsetse flies have an arsenal of immune defenses to resist each stage of the trypanosome infectious cycle, and thus are relatively refractory to trypanosome infection. [67] Among the host flies' defenses is the production of hydrogen peroxide, [68] a reactive oxygen species that damages DNA. These defenses limit the population of infected flies.
The threat to mayflies applies also to their eggs. "Modest levels" of pollution in rivers in England are sufficient to kill 80% of mayfly eggs, which are as vulnerable to pollutants as other life-cycle stages; numbers of the blue-winged olive mayfly (Baetis) have fallen dramatically, almost to none in some rivers. The major pollutants thought ...
