Chironomidae (Diptera) of the Šventoji and Žeimena sub-basins in Lithuania.

Background: Chironomidae, commonly known as non-biting midges, are key indicators of the health and biodiversity of freshwater ecosystems. They are also one of the most abundant and diverse groups of aquatic invertebrates. Although Chironomidae are ecologically important, abundant and diverse, there has been limited focused research on this group in Lithuania.

Beetles (Coleoptera) in deciduous dead wood tree species trunks in Lithuania.

We present a list of beetles that emerged from wind-felled tree trunks of several tree species, including European ash (), aspen (), common oak (), birch ( sp.), small-leaved linden () and black alder (). Four hundred and ninety species and 60 families of beetles were collected using trunk-emergence type traps.
