Invertebrates

Invertebrates Hall consists of 15 separate showcases. They are systematically arranged by representatives of the invertebrate fauna. The showcases numbering is clockwise, entering the hall from left to right. The exhibition is a mix of wet and dry preparations of rare and distinctive species. Species which are very rare or too small to display are presented via photographic material. The hall shows the complete system of Bulgarian insect species by families. A separate module is collection of the largest and most interesting insects in the world. The largest beetle (162), night butterfly (112), birdwing butterflies (and all butterfly species), mantis (130), stick (193), ant (129), dragonfly (195) and damselfly(121).

• A beehive with bees, which collect pollen outside the museum through a special hole in the wall.
