PIN. We examined 65 inclusions kindly lent to us by Prof. Alexandr Rasnitsyn. All specimens belong to the Orthocladiinae – the most common subfamily of Chironomidae in amber deposits worldwide ( Zelentsov et al., 2012 ). In this series we found eight males. Seven specimens belong to previously

Biology and Ecology of the Aquatic Orthocladiinae

Chironomidae Larvae of the Netherlands and Adjacent Lowlands

Chironomids are a group of non-biting midges, the larvae of which are important in aquatic ecosystems. The subfamily Orthocladiinae is well represented in flowing water. This books contains information about their life cycle, feeding behaviour and their response to environmental factors. Chironomidae Larvae, Vol. 3: Orthocladiinae presents a wealth of information for scientific and practical purpose.

The subfamily Orthocladiinae is especially well represented in flowing water. Most of the species need a good supply of oxygen and few larvae are bottom dwellers. Many species emerge early in spring and may be scarce in summer. Other species live in stagnant and even temporary water bodies.

• information about the life cycle and feeding behaviour of the larvae and their response to environmental factors such as oxygen conditions, current velocity and saprobity
• special attention to the interrelations between these factors
• general and specific aspects of the systematics, biology and ecology the genera and species
• nomenclature and identification

An invaluable tool for aquatic ecologists and water quality management.

primitive orthoclads show that either the more plesiomorphic genera of Orthocladiinae form a monophyletic group or Pro- psilocerus may be more closely related to less plesiomorphic groups. Chasmatonotus Loew forms its likely sister group. The genus is monophyletic in all cladograms. A synapomorphic diagram
