The Fen Raft Spider (Dolomedes plantarius) belonging to the Family Pisauridae lives around the margins of waterbodies, in peatlands and swampy forests. They vigorously glide over the water and hide in case of danger. Fen raft spiders hunt for various arthropods fallen into the water.
Fen raft spiders are found in swamps and forests of Western, Central, and Eastern Europe. However, despite a wide distribution of the species, it is difficult to estimate its population because of similarity with the raft spider.
The Ladybird Spider(Eresus cinnaberinus) of the familyEresidae is the most beautiful spider of distinctive appearance found in Lithuania. Due to a hidden lifestyle it is especially rare. The lady bird spiders usually hunt for big beetles having a firm chitin shell (dung-beetles, skippers). They live in southern slopes protected from wind, in dry locations and sandy soil.
This species is included into the Red Lists of majority European countries. In Lithuania, it was discovered in 1999 and 2002 in Jurbarkas District.
