Hypolimnas bolina, the great eggfly, [1] [2] common eggfly, [2] varied eggfly, or in New Zealand the blue moon butterfly, [3] is a species of nymphalid butterfly found from Madagascar to Asia [1] and Australia.
Eggs of black-veined white (Aporia crataegi) on apple leaf A butterfly from the genus Euploea, laying eggs underneath the leaf. Butterfly eggs are protected by a hard-ridged outer layer of shell, called the chorion. This is lined with a thin coating of wax which prevents the egg from drying out before the larva has had time to fully develop.
The top of the egg is depressed and forms a small central cavity called micropyle through which the egg is fertilised. [11] The micropyle is situated on top in eggs which are globular, conical, or cylindrical; in those eggs which are flattened or lenticular, the micropyle is located on the outer margin or rim.
A Lepidoptera specimen drawer in a museum collection in Poland Another Lepidoptera specimen drawer in a museum collection in Poland. Lepidopterology (from Ancient Greek λεπίδος (lepídos) ' scale ' πτερόν (pterón) ' wing ' and -λογία [1]) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell.
This neotropical butterfly is found in Central and South America, including the Cerrado which is a vast tropical savanna in Brazil. [5] Other locations include Mexico [2] and Venezuela. [6] Ancestors of the Morpho menelaus butterfly may have been distributed in the Andean regions. [4] Morpho menelaus is one of the six species of Morpho in Costa ...
These are thought to protect the plant as the butterfly avoids laying eggs near eggs already on a host plant, to give her own eggs the best chance of survival. A later example is the mimicking of a mammalian hormone by an ant toxin which causes long-lasting hypersensitivity, Gilbertian mimicry at a molecular level.
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...
