A study conducted in pine canopies in the Berezinsky Biosphere Reserve, Belarus, in 1989-90 revealed 17 species of Neuropteroidea of the families Raphidiidae, Coniopterygidae, Hemerobiidae and Chrysopidae, and 7 species of Coccinellidae. The most numerous species included Hemerobius stigma, Myrrha octodecimguttata and Anatis ocellata.
