A fundamental prerequisite for understanding and protecting biodiversity is the construction of a high-quality faunal database. The primary objective of this study was to address knowledge gaps in the biodiversity of the family Psychodidae in Estonia. Faunistic data on 45 species of moth flies (Diptera: Psychodidae) from Estonia are presented, incl...

Mycetobia obscura Mamaev, 1968 and the subfamily Mycetobiinae (Diptera, Anisopodidae) are recorded from Esto-nia as well as from the Baltic States for the first time. The morphology and biology of the species is briefly discussed and detailed photographs of the general habitus of M. obscura and both the male and female terminalia are provided.

Potential Dutch elm disease vector beetle species were caught with pheromone bottle traps and handpicked in 2019: in total, seven species and 261 specimens were collected. The most common was Scolytus triarmatus, but by percent, the incidence of Ophiostoma novo-ulmi was highest in Scolytus scolytus, followed by Xyleborinus saxesenii and S. triarmat...

The current knowledge of pseudoscorpions in Estonia is summarized, based on specimens preserved in various Estonian collections and new material collected from 1993 to 2015. Altogether 474 studied specimens belonged to 14 species, including nine species recorded from Estonia for the first time. Supplemented by Apocheiridium rossicum, listed by lite...

The article presents an annotated list of 99 new beetle species for Estonia (mainly woodland ones) along with their faunistic data. Most of the material has been collected by the author using trunk window traps within the framework of various research and monitoring projects in 2011–2015. In addition, the work comprises a number of unpublished new...

There are many factors which affect durability of wood in the existing timber structures. One of the most important factors affecting durability is biological, especially the wood-rotting fungi and wood-boring insects. This paper gives an overview about fieldworks on Ruhnu Island and investigations on damages caused by house longhorn beetle and com...

The assemblages of Coleoptera were studied in the burnt pine-dominated (Pinus sylvestris) forests of northern Estonia during the first two years after fire. Ten window traps attached to the trunks of trees and 20 pitfall traps set up in soil surface were used for collecting insects in 2007 and 2008. Altogether, 22,194 specimens of Coleoptera were c...

The article presents faunistic data on 85 species of Coleoptera new to the Estonian fauna. Most of the material has been collected within the framework of various research and monitoring projects carried out in Estonian nature reserves (1998-2009). A new type of trunk window trap, designed by the author in 2004 mainly for monitoring purposes, has b...

Fire is a disturbance agent, which drastically changes habitats for living organisms in the forests. In 2006, large forest fires occurred in Ida-Viru County, north-eastern Estonia. The assemblages of Coleoptera were studied in the burnt pine-dominated forests in the first year after fire. Six window traps attached to the trunks and 12 pitfall traps...

According to collection data the fauna of Estonian bark beetles comprises 65 species, whereas the last added species has been Scolytus triarmatus (Egg.). The find of the species in Southern Estonia was concurrently the first find in the Baltic region. In Northern and Central Europe, this species has been misidentified for a long time as S. scolytus...

We are 28 co-authors representing 25 European countries, who have collected data on a threatened beetle associated with tree hollows. Osmoderma eremita (SCOPOLI, 1763) (Coleoptera: Scarabaeidae). This project has arisen from our own initiative, based on the belief that entomology and nature conservation would do better with stronger co-operation be...

Research, monitoring and development of preservation strategies for threatened species are often limited by national borders even though a global perspective would be more appropriate. In this study, we collected data on the occurrence of a threatened beetle, Osmoderma eremita, associated with tree hollows in 2,142 localities from 33 countries in E...

This paper summarises the results of research on Coleoptera communities conducted over 11 years (1990–2000) in an intensively managed pine (Pinus sylvestris) forest area of the Räpina forest district in south Estonia. Using different traps (baited ground traps, window traps and pitfalls) and traditional collection methods, more than 127,800 insects...

The collection specimens of the genus Dorcatoma Herbst, 1792 were revised for Estonia. A substantial part of the material was reared from fruiting bodies of bracket fungi. Seven species of the genus are found in the country. Five of them, D. flavicornis F., D. substriata Hummel, D. punctulata Mulsnat & Rey, D. robusta Strand and D. lomnickii Rtt. a...
