Abstract

The paper presents information about the occurrence of digger wasps in the Pomeranian Lake District and on the Baltic Coast. Samples were collected from 1983 to 2016. The study yielded a total of 127 species (about 53% of Polish fauna) belonging to 35 genera; were recorded 22 species are new for the Baltic Coast and 2 are new for the Pomeranian Lake District. Also, 22 of the species identified are on the Red List of Threatened Animals in Poland: Ammophila pubescens Curtis, 1836, Bembix rostrata (Linnaeus, 1758), Cerceris ruficornis (Fabricius, 1793), Crossocerus congener. (Dahlbom, 1845), C. heydeni Kohl, 1880, C. pullulus (A. Morawitz, 1866), C. styrius (Kohl, 1892), C. tarsatus (Shuckard, 1837), Didineis lunicornis (Fabricius, 1798), Dolichurus corniculus (Spinola, 1808), Dryudella pinguis (Dahlbom, 1832), Ectemnius fossorius (Linnaeus, 1758), Gorytes fallax Handlirsch, 1888, Harpactus tumidus (Panzer,1801), Lestica alata (Panzer, 1797), Mimumesa beaumonti (van Lith, 1949), Miscophus ater Lepeletier, 1845, Nysson niger Chevrier, 1868, Oxybelus variegatus Wesmael, 1852, Pemphredon austriaca (Kohl, 1888), Tachysphex fulvitarsis A. Costa, 1867 and T. psammobius (Kohl, 1880).

Highlights

In the world fauna, there are 10,007 species of digger wasps (Pulawski 2019), 241 of which are found in Poland (Olszewski et al in press)
The data in the present paper provide information on the occurrence of digger wasps in the Pomeranian Lakeland and on the Baltic Coast collected by the second author in the years 1983–2016
The first information on the occurrence of individual sphecid wasps in Pomerania is contained in Siebold (1839) and Brischke (1862, 1865, 1888); more accurate data from the late nineteenth century to World War II from the Pomeranian Lakeland are included in the papers by Lüderwaldt (1897), Müller (1918) and Paul (1941)

Summary

Introduction

There are 10,007 species of digger wasps (Pulawski 2019), 241 of which are found in Poland (Olszewski et al in press). These insects are morphologically diverse, with sizes ranging from 2 to 30 mm. The data in the present paper provide information on the occurrence of digger wasps in the Pomeranian Lakeland and on the Baltic Coast collected by the second author in the years 1983–2016. The first information on the occurrence of individual sphecid wasps in Pomerania is contained in Siebold (1839) and Brischke (1862, 1865, 1888); more accurate data from the late nineteenth century to World War II from the Pomeranian Lakeland are included in the papers by Lüderwaldt (1897), Müller (1918) and Paul (1941)
