They form a ring-like structure for the attachment of genital parts and a pair of lateral clasping organs (claspers, valvae (singular valva), or ‘harpes’). The male has a median tubular organ (called aedeagus or phallus) which is extended through an eversible sheath (or ‘vesica’) to inseminate the female.
What do moth genitals look like?
Male moths have claspers – or spatula like folds of their genitalia that physically grab onto the female while mating. Frequently you can see the outline of these claspers which look like a pair of folded hands on the underside tip of the abdomen.
What are the female reproductive organ of a butterfly?
We focus on the physiology of a complex female reproductive adaptation in butterflies and moths: a stomach-like organ in the female reproductive tract called the bursa copulatrix that digests the male ejaculate (spermatophore). Little is known about how the bursa digests the spermatophore.
What are insect genitalia called?
The female has a penis-like protrusion called a gynosome, which is erectile and curved. The male has no such organ; he has an internal chamber instead. When she penetrates him during sex, he delivers sperm into a duct in her gynosome, which leads to a storage organ.
What is a defining characteristic of Lepidoptera?
The scientific name of the order, Lepidoptera, is derived from one of their main characteristics, namely their having wings covered in tiny scales (from the Greek lepidos = scale and pteron = wing). … The leg and wings are attached to the thorax. In a few species of moths, the females have evolved to become wingless.
What kind of mouthparts do Lepidoptera have?
While mandibles or jaws (chewing mouthparts) are only present in the caterpillar stage, the mouthparts of most adult Lepidoptera mainly consist of the sucking kind; this part is known as the proboscis or haustellum. A few Lepidoptera species have reduced mouthparts and do not feed in the adult state.
Do moths have sperm?
Weighing more than 10 percent of the male moth’s body mass, the spermatophore contains enough sperm to fertilize hundreds of U. ornatrix eggs, nutrients to help the female produce numerous healthy eggs and PAs, now known to protect the female as well as her eggs, González says.
Does Butterfly have oviduct?
Ovaries and Ovarioles: Lepidoptera have two ovaries, each of which consists of four ovarioles. Oocytes (eggs) are produced here. Common oviduct: The two ovaries connect to a tube called the common oviduct.
What comes out of a moths butt?
But when preparing to mate, four tubular, translucent scent glands, or coremata, inflate like balloon animals from his behind. Some male moths and butterflies have these coremata, or “hair-pencils.” They use them to expel pheromones to attract mates, and the hairs waft the smell toward the females.
What is the purpose of insect integument system?
An insect’s exoskeleton (integument) serves not only as a protective covering over the body, but also as a surface for muscle attachment, a water-tight barrier against desiccation, and a sensory interface with the environment.
Where are Hymenoptera found?
Except in the polar regions, they are abundant in most habitats, particularly in tropical and subtropical regions. Collectively, the Hymenoptera are most important to humans as pollinators of wild and cultivated flowering plants, as parasites of destructive insects, and as makers of honey.
Where are Lepidoptera found?
Lepidopterans live on every continent except Antarctica. Though they are far more numerous and diversified in the tropics, some species survive at the limits of polar vegetation. There are many successful species in nearly every environment, from arid deserts and high mountaintops to marshes and tropical rainforests.
What are Lepidoptera scales made of?
The powder is actually tiny scales made from modified hairs. Moths, like butterflies, belong to the order Lepidoptera, which means ‘scale wing’. The scales are pigmented but they also contribute to the pattern on the wings by diffracting light through a complex microscopic structure of ribs and holes.
What Mouthpart does a caterpillar have?
Caterpillar mouthparts basically consist of an anterior flap (labrum), a pair of chewing jaws (mandibles), a pair of complex first maxillae, and a pair of similar second maxillae joined together behind the mouth to form a structure called the labium.
How do mouthparts function?
In all “primitive” insects, the mouthparts are adapted for grinding, chewing, pinching, or crushing bits of solid food. These are known as “mandibulate” mouthparts because they feature prominent chewing mandibles. … Mandibles — a pair of jaws for crushing or grinding the food.
Do butterflies get pregnant?
During the mating process, when their bodies are joined, the male passes sperm to the female. As the eggs later pass through the female’s egg-laying tube, they are fertilized by the sperm. The male butterfly often dies soon after mating.
Are butterflies male?
Males tend to have a more slender abdomen and females tend to have larger rounded abdomens. … Males have a round black dot in the hindwing that the females do not have. Often females are slightly larger in size than the males. Some species exhibit sexual dimorphism, meaning that the two sexes look completely different.
How do butterflies mate?
They mate, joining the tips of their abdomens, and the male passes sperm to the female in order to fertilize her eggs. The female then lays her eggs on plants or on the ground. … Generally, female butterflies choose which males they want to mate with and males therefore compete for the attention of females.
Are butterflies asexual?
The short answer to the question is that all known species of butterflies reproduce sexually most of the time. … A few butterfly species can reproduce asexually as well, but it’s never the main means of reproduction because it comes at the cost of genetic variation (the offspring tend to be clones of the mother).
What is parthenogenesis in insect?
Parthenogenesis is a form of asexual reproduction whereby offspring are produced without the embryo being fertilised by a male. … Other insects capable of reproducing parthenogenetically include some species of aphid, ant, bee and parasitic wasp. Many aphids reproduce parthenogenetically.
Is Creatonotos Gangis real?
First, the bad news: It’s real. The moth is called Creatonotos gangis, and it lives in parts of Southeast Asia and Australia.
Where does the Creatonotos Gangis moth live?
Distribution. Creatonotos gangis lives in South East Asia and parts of Australia. Its Asian distribution includes eastern Indonesia, India, Iran, Sri Lanka, China, Japan, Thailand and New Guinea.
Do moths poop?
Adult butterflies do not urinate or defecate (or “go to the bathroom”). … When gypsy moths (Lymantria dispar) infest a forest, the defecation of the caterpillars sounds like rain. Occasionally adult butterflies drink so much they must emit a fine liquid spray from the tip of their abdomen.
What is integument made up of?
The integument consists primarily of the skin and its derivatives. Skin is a functional unit composed layers of fairly distincy epidermis (derived from ectoderm) and dermis (derived from the dermatome of somites) that are separated by the basement membrane (Fig. 6.1, p. 199).
What tissues make up the hypodermis?
Connective tissue and adipose tissue mostly make up the hypodermis.
What is insect exoskeleton?
An exoskeleton is a hard covering that supports and protects the bodies of some types of animals. … Insects have exoskeletons made of a substance called chitin. The exoskeletons of crabs, lobsters, shrimp, spiders, ticks, mites, scorpions, and related animals are also made of chitin.
What do Hymenoptera feed on?
Diet. Different species of Hymenoptera show a wide range of feeding habits. The most primitive forms are typically phytophagous, feeding on flowers, pollen, foliage, or stems. Stinging wasps are predators, and will provision their larvae with immobilised prey, while bees feed on nectar and pollen.
What does Hymenoptera name mean?
Abstract. Hymenoptera is one of the largest orders of insects and includes many species of bees, wasps, hornets, sawflies, and ants. The word Hymenoptera is derived from the ancient Greek words for hymen, meaning membrane, and pteron, translated to wing. … Hymenoptera is one of the largest orders of insects.
What is Hymenoptera venom?
All Hymenoptera venoms contain low-molecular-weight substances, such as biogenic amines, phospholipids, amino acids, and carbohydrates, as well as peptides, such as melittin, apamin, and kinins, which contribute to the toxic effect but which—except melittin—are probably irrelevant with regard to allergies.
