Screwworm females lay 250–500 eggs in the exposed flesh of warm-blooded animals, including humans, such as in wounds and the navels of newborn animals. The larvae hatch and burrow into the surrounding tissue as they feed.
Females usually lay between four to six (rarely two to seven) pale bluish-green, brown-blotched eggs. [41] Incubation is about 18 to 21 days, by the female only. The male may stand or crouch over the young, sheltering but not actually brooding them. [78] The young fledge at 35 to 49 days, and are fed by both parents. They stay with their ...
Corvids can lay between 3 and 10 eggs, typically ranging between 4 and 7. The eggs are usually greenish in colour with brown blotches. Once hatched, the young remain in the nests for up to 6–10 weeks depending on the species. Corvids use several different forms of parental care, including bi-parental care and cooperative breeding.

The fly commonly infects humans by laying its eggs on wet clothes, left out to dry. [10] The eggs hatch in one to three days and the larvae (which can survive without a host for up to 15 days) then burrow into the skin when the clothes are worn. [1] A prevention method is to iron all clothes, including underwear, which kills the eggs/larvae ...
Parasitoid use of viruses: parasitoid wasps lay their eggs inside host caterpillars; to keep the caterpillar's immune system from killing the egg, a virus is also "laid" with the eggs. Two unrelated wasps use this trick. [153] Short-lived breeders: species that are in the juvenile phase for most of their lives.
The theory gained steam on Facebook, TikTok and Twitter in recent weeks, with some users reporting that their hens stopped laying eggs and speculating that common chicken feed products were the cause.
Hooded crow (Corvus cornix) in flight Jungle crow (Corvus macrorhynchos) scavenging on a dead shark at a beach in Kumamoto, Japan. Medium-large species are ascribed to the genus, ranging from 34 cm (13 in) of some small Mexican species to 60–70 cm (24–28 in) of the large common raven and thick-billed raven, which together with the lyrebird represent the larger passerines.
In the case of eggs, this means that r-strategists lay large numbers of eggs, while K-strategists take care to protect a smaller number of eggs. Lacebugs of the genus Corythucha are subject to egg predation by obligate egg predators like mirid bugs , pirate bugs , and thrips , and respond to it in varying ways.
