Caligo atreus


Caligo Atreus is a butterfly from the family of the nymphalidae and is known for its huge eyespots on the lower part of the hindwings, which resemble almost full-size owlТs eyes. Such «eyes» can frighten or distract the attention of an attacking predator.

It has wide wings, with a wingspan of 14–16 cm. The blue color on the wings of this butterfly has the ability to shimmer depending on the refraction angle of light. The pattern on the wings of the female and the male differs slightly, but the females are often larger and their color is somewhat more modest. Caligo Atreus is the inhabitant of dense tropical forests of Central America. Butterflies of this species are active no more than 20 minutes a day in the morning and evening. They feed on over-ripe fruit, giving particular preference to over-ripe bananas. Caterpillars live in joint groups and are nocturnal, causing serious damage to banana plantations, mangoes and other fruit plantations.

Samia luzonica


Butterfly Samia luzonica from the family Saturniidae is found only on the Philippine Islands and Sulawesi Island. The butterfly gas a wingspan of 10–12 cm. Females are larger in size than males, the color of the wings in males is darker than in females. The peak of the butterfly’s flight is in

October — March and May — August. Species of the silkmoth genus Samia are often used in commercial sericulture.

Papilio lowi and Papilio memnon are representatives of large Asian swallowtails (Papilionidae), the wingspan of Papilio lowi is about 10–15 cm, and of Papilio memnon Ц 12–15 cm.

Papilio lowi , female


Papilio lowi is found in Borneo, Indonesia and the Philippines. Females are larger in size than males. Males are sometimes called the black prince for the deep black color of the wings. Females front wings are covered with a light silver-beige coating. Caterpillars feed on citrus plants such as lemons, oranges, tangerines. Adult (adult insect) longevity is up to 7 days.

Papilio memnon


Papilio memnon is distributed throughout Myanma, Japan and Indonesia, in the Himalayas. Flower nectar is not the main food of this butterfly — for its vital activity it needs various mineral substances, the source of which are the waste products of mammals and birds and even decomposition products of dead animals. The only condition is that all this should be fresh and moist, otherwise the butterfly will not be able to suck out the substances it needs.

The butterflies have been handed over to the Museum by Victoria Alexandrovna Dubinina, employee of the Natural Sciences Department.

The museumТs collection of tropical butterflies is growing and in future will be on display at exhibitions.
