✦ Synopsis

The colonization by Chirononzus spp. of two ponds filled after a dry period was investigtJted. Field data were collected by means of quantitative benthic samples and emergence traps. C. nielanescens, C. awnulnrius, C. ripurius, C. yiger, C. luridus, C. ohtusidens, C. pluniosus, C. dovsrilis and Cantpfochironomics tentcrns were determined cytotaxonomically in ponds investigated. C. nielnnescens and C. awuularius appear to be the most characteristic species coloniziiig in high numbers in newly filled ponds. Larvae of C. annularius grew more slowly in ponds compared with the former one which resulted in a characteristic succession of both larval types. Most species mentioned disappeared conipletely from the ponds investignted after the metamorphosis of a single cohort. They were replaced by C. plurnosus which was often attended by C. nnnularius in smaller ponds.
