Species of Bibionidae from Baltic amber are reevaluated based on newly discovered material, and a key to the species is given. Bibio succineus sp. nov. is described based on one male specimen, this is the first Bibio named from Baltic amber. The male

The Diptera family Bibionidae has a rich fossil record from the Tertiary, however little is known about this family in the Mesozoic. Recently, a number of specimens have been found in mid-Cretaceous Myanmar amber, dating from about 99 MYr BP. I repor

In temperate forests, red wood ants (Formica aquilonia) are considered ecosystem engineers affecting ecosystem properties and functions. Possible effects of F. aquilonia ants on species communities of invertebrates and plants were studied in the pine
