To the knowledge of insects, pollinators of Sorbus aucuparia Linnaeus, 1753 and Aronia mitschurinii A.K. Skvortsov et Maitul., 1982 in Moscow Region, Russia

Composition of insect species pollinating Sorbus aucuparia and Aronia mitschurinii in Moscow Region, Russia was studied. It was collected 39 species – representatives of 4 orders and 21 families. The hypothesis that these two plants with same inflorescences and blossoming simultaneously are visited by the same insect species was not proved: 18 species were captured only on S. aucuparia and 16 species only on A. mitschurinii. Insects demonstrated selectivity towards aboriginal (Sorbus) and adventive (Aronia) plants. Only five species were registered on both plants: Bombus ruderarius Müller, 1776, Andrena haemorrhoa (Fabricius, 1781), Bellardia viarum obineauDesvoidy, 1830, Anthrenus scrophulariae Linnaeus, 1758 and Anaspis frontalis (Linnaeus, 1758). Sorbus aucuparia was more attractive for Diptera from the families Calliphoridae and Milichiidae, and Aronia mitschurinii – for Anthomyiidae, Calliphoridae and Sarcophagidae. Selectivity was discovered at species level also: Andrena ruficrus Nylander, 1848 and Myopa polystigma Rondani, 1857 visited Aronia mitschurinii only and Andrena subopaca Nylander, 1848 and Myopa testacea (Linnaeus, 1767) – Sorbus aucuparia. The majority of collected insect species are polyphagous. Additional data on other plants visited by the same insects during the period of bloom of Sorbus and Aronia are given, including those from the genera Malus, Spiraea, Pyrus, Prunus, Rosa, Rubus, Cerasus Crataegus, Barbarea and Taraxacum

To the biology of muscid flies of the genus Limnophora Robineau-Desvoidy, 1830 (Diptera: Muscidae)

Morphological description of larva and puparium of Limnophora patellifera (Villineuve, 1911) and additional data for larva and puparium of Limnophora riparia (Fallén, 1824) are given for the first time. Most distinct differences in the species are discovered in the morphology of the pupariu

New data on the biology and distribution of agromyzid fly Phytomyza pastinacae Hendel, 1923 (Diptera: Agromyzidae)

The study of insects-pests of giant hogweed Heracleum Sosnowskyi Manden in Moscow Region allowed to discover agromyzid species Phytomyza pastinacae Hendel, 1923 (Diptera: Agromyzidae), new for the fauna of Russia. Larvae of this species were previously registered in leaves of different Apiaceae but the development in Heracleum Sosnowskyi is registered for the first time

A description of male of the shore-fly Notiphila (Agrolimna) bivittata Cogan, 1968 (Diptera: Ephydridae)

A male of the shore-fly Notiphila (Agrolimna) bivittata Cogan, 1968 is described for the first time. The species belongs to the subgenus Agrolimna Cresson, 1917. However two developed posterolateral projections of epandrium of male terminalia and absence of central projection are not typical for Afrotropical representatives of this subgenus, though these characters are known for some Holarctic species. The species is registered in Ethiopia for the first tim

Tachinid flies (Diptera: Tachinidae), pollinators of aboriginal and alien species of the umbel plants (Apiaceae) in Moscow Region (Russia)

The role of tachinid flies (Diptera: Tachinidae) as pollinators of aboriginal and alien species of the umbel plants (Apiaceae) in Moscow Region (Russia) is discussed. From total number of 34  tachinid flies, 11  species were observed on aboriginal plants only. Five species, Myxexoristops blondeli (Robineau-Desvoidy, 1830), Pachystylum bremii Macquart, 1848, Neaera laticornis (Meigen, 1824), Actia pilipennis (Fallén, 1810) and Eriothrix rufomaculatus (De Geer, 1776) were collected on Heracleum sosnowskyi exclusively, and two species, Medina collaris (Fallén, 1820) and Policheta unicolor (Fallén, 1820), on Pastinaca sativa only. More than half of examined tachinids (23 species) demonstrated selectivity to the host plant, each of them pollinated one plant species. Eleven tachinid species pollinated more than 1 plant species. The least selectivity to plant species was stated for tachinids Solieria pacifica (Meigen, 1824) and Strongygaster globula (Meigen, 1824), registered on 5 Apiaceae species as well as on plants from other families
