The aim of this house is to awaken a fascination for the creepy-crawly world of the anthropods. Such different animals as insects, millipedes, crustaceans, scorpions and spiders belong to the anthropod family. The first room in the three sections of the Insectarium is dedicated to the diversity of the anthropods – a group of animals some 80 percent of all known and still living animals belong to! In the central area the Butterfly Hall shows the wonderful world of the butterfly and in the third room the subject is the relationship between insect and human being.

Amongst others, the following animals are to be seen in the Insectarium: hairy tarantulas, diligent leaf-cutting ants, spiny giant prickly stick insects, fossil horseshoe crabs, hissing cockroaches, long-legged golden web spiders, Colorado beetles that infiltrated the country, strange stick insects, worm-like centipedes, rainbow rose flower beetles, black widow spiders, leaf insects, long-legged locusts, poisonous scorpions, busy bees, pestilential Mediterranean flour moths and iridescent butterflies. All of them invite the visitors to occupy themselves with this world, which is so strange to us humans.

The Butterfly Hall in the centre of the Insectarium does not only house the lovely butterflies, but also a variety of interesting plants. It is like a tropical garden with palms, luxuriant greenery and a colourful and magnificent array of blossoms. The plants have been chosen according to what the voracious caterpillars do not like to eat, because otherwise the House would be eaten bare in no time at all. For the butterflies, though, there are plenty of nectar plants as feeding or landing places, such as hibiscuses, cottonweed plants, lantana (Spanish Flag plants) and many others.
