W pracy opisano cykl życiowy wszystkich występujących w Polsce gatunków muchówek z rodzaju Lipara (L. lucens, L. similis, L. rufitarsis i L. pullitarsis). Opis każdego z nich zawiera szczegółowe informacje dotyczące wyboru miejsca na roślinie w okresie składania jaj, sposobu żerowania larw, rodzaju spożywanego pokarmu oraz budowy galasów. Etologia larw pierwszego i drugiego stadium, została po raz pierwszy opisana. Podano przyczyny opuszczania źdźbła wyłącznie przez jednego owada dorosłego. Wyjaśniono zjawisko występowania larw i poczwarek w galasach nietypowych dla własnego gatunku.
The book describes the life cycles of all species of Lipara flies (L. lucens, L. similis, L. rufitarsis and L. pullitarsis) occurring in Poland. The description of each species includes detailed information on the choice of locations for laying eggs on a reed stem, larval feeding behaviour, type of food consumed, and structure of galls. The etology of first- and second-instar larvae is presented for the first time. Explanation is given for the fact that only one adult Lipara individual leaves a stem. The causes underlying the occurrence of larvae and pupae in galls that are not typical of particular species are also explained.
