Monarch butterflies flying and sipping nectar from milkweed flowers. The adult's wingspan ranges from 8.9 to 10.2 centimetres (3.5 to 4.0 in). [10] The upper sides of the wings are tawny orange, the veins and margins are black, and two series of small white spots occur in the margins. Monarch forewings also have a few orange spots near their tips.
Danaus chrysippus, also known as the plain tiger, [1] [2] African queen, [2] or African monarch, is a medium-sized butterfly widespread in Asia, Australia and Africa. [2] It belongs to the Danainae subfamily of the brush-footed butterfly family Nymphalidae .
Pteromalus cassotis is a species of parasitic wasp in the family Pteromalidae that parasitizes the chrysalides of monarch butterflies. They are gregarious parasitoids, meaning a single female lays many eggs in a single host. Research into this species has documented that up to 425 adult wasps can emerge from a single chrysalis.
The oviducts of the female join to form a common duct (called the "oviductus communis") which leads to the vagina. [55] [56] When copulation takes place, the male butterfly or moth places a capsule of sperm (spermatophore) in a receptacle of the female (called the corpus bursae).
The ZW sex-determination system is a chromosomal system that determines the sex of offspring in birds, some fish and crustaceans such as the giant river prawn, some insects (including butterflies and moths), the schistosome family of flatworms, and some reptiles, e.g. majority of snakes, lacertid lizards and monitors, including Komodo dragons.
The male passes a spermatophore to the female; to reduce sperm competition, he may cover her with his scent, or in some species such as the Apollos plugs her genital opening to prevent her from mating again. [40] The vast majority of butterflies have a four-stage life cycle: egg, larva (caterpillar), pupa (chrysalis) and imago (adult
[4] [5] Male butterflies can also have O. elektroscirrha, and can scatter the dormant spores onto milkweed leaves as they fly around, or pass them onto females during mating. [6] Spores of O. elektroscirrha are ingested by the caterpillars when they eat their egg chorion (shell) after they hatch, and when they feed from infected milkweed.
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
