Identification guide of Finnish Opiliones and Pseudoscorpions

+ Show information

Basic project information

There are 12 species of harvestmen (Opiliones) and 16 species of pseudoscorpions (Pseudoscorpiones) currently known to occur in Finland. Both species groups are beasts that prey mainly on smaller-sized insects and arachnids. Majority of Finnish harvestman and pseudoscorpion species live in forest habitats, mainly in forest litter. Harvestmen can be found in lush, moist forests, pseudoscorpions prefer deciduous and old forests. Some pseudoscorpions inhabit decaying wood, and these species have declining populations due to the generally small amount of dead wood in Finnish forests.

There are no identification guides of harvestmen and pseudoscorpions in Finnish. The lack of good-quality identification book has limited the amount of enthusiasts in the field. Generally, both species groups are poorly studied in Finland, and hardly anything is known about their ecology. In this project the aim is to produce a well-written identification book with descriptions and identification keys for all the Finnish harvestman and pseudoscorpion species, including basic knowledge on the distribution and ecology of the species. The book will be completed in 2014.
