Here you will
see various live invertebrates including insects which belong to 5 different
orders living on 5 continents, tropical Scorpions and a tarantula. Beautiful
butterflies continuously leave their cocoons in a special tiny greenhouse. A carnivorous
plant helps to reduce the number of small flies. There you can also notice
a moth Samia Cynthia ('Ailanthus silkmoth').
Most butterflies
usually successfully reproduce and lay eggs in our greenhouse. In 7-10 days
caterpillars hatch their eggs. Newborn caterpillars are very small, only about
3 mm long. They reach a much larger size in about 3-4 weeks time. These
caterpillars produce silky cocoons, so they are often called silkworms.
A
greenhouse full of amazing butterflies always attracts much interest.
It’s not
always easy to find a stick insect in a terrarium despite its impressive size
which is around 10 cm for an imago.
The larvae
of these beetles are often specially grown to feed insect-eating pets. These
larvae are harmless; they feed on various organic residues, although they are
often used in horror movies.
In June
2015 nymphs of the scorpion Heterometrus spinifer were born in our Nature Live
Exposition. They crawled up onto their mother's back right after their
birth.
Here they
spent 2 weeks waiting for their first moulting. In the near future the main
task of little scorpions is to eat well and grow, periodically changing their
exoskeleton. In 2-3 years they will finally grow up, reaching a length of 15
cm. The photo shows one of the nymphs after its 3rd moulting (next to the
discarded outer skeleton).
