Dragonflies are among the most beautiful of insects. Peninsular Malaysia and Singapore are home to more than 230 species (twice the number found in Europe). They include some of the most exquisite forms found anywhere in the World. They occur wherever there is suitable fresh water habitat. Many species frequent the borders of garden ponds in our largest cities, perching on lily pads with glowing red bodies in striking contrast to their green platform. Others haunt swift clear streams in virgin rainforest, while yet others are confined to blackwater swamps. A few occur deep in the forest understorey, far from streams or pools, where they breed in the water accumulated in cavities in tree trunks. This book figures 98.7% of species known from Peninsular Malaysia and Singapore. For most, coloured drawings of the whole insect (omitting one pair of wings) are provided. Where necessary, coloured or monochrome drawings showing diagnostic features are also included. For some species, especially small Zygoptera (damselflies), only detailed structures are figured, as the general resemblance between close species is strong. A wide range of larval types is also figured.
