ABSTRACT
Pre-pupation selectivity of inorganic substrate grain size for case building by trichopteran larvae, Hydropsyche pellucidula, was estimated on the basis of laboratory experiment and field data. Among four inorganic substrate fractions (fine and coarse sand, fine and coarse gravel) individuals of H. pellucidula that had inhabited in coarse sand and fine gravel were able to complete their life cycle.

Praca prezentuje eksperyment laboratoryjny dotyczący wybiórczości odpowiedniej średnicy ziaren potrzebnych do budowy domku poczwarkowego przez larwy Hydropsyche pellucidula znajdujące się w ostatnim stadium rozwojowym. Badano zdolność budowlaną dla czterech frakcji ziaren oraz sukces w zamknięciu cyklu życiowego
