The Macrosiphini of Scandinavia are treated in vol. IV, in the present vol. V and the coming vol. VI, with descriptions and illustrations.
This is the last volume dealing with the aphids of Fennoscandia and Denmark. It treats the remaining species of Aphididae and the family Lachnidae and contains a host plant index and an index to all Latin names of the species treated in all six volumes. Like the first five volumes it contains keys and illustrations.

This volume treats part of Macrosphini (Aphididae: Aphidinae), with keys to all genera occuring in Scandinavia or expected to be found there in the future and descriptions of some of them, including "Anuraphis, Brevicoryne, Coloradoa and Cavariella; Myzus, Nasonovia, Capitophorus" and "Macrosiphum" will be treated in the fifth volume, "Uroleucon" and "Megoura" in the sixth volume together with Lachnidae. It includes several drawings, taxonomical and biological notes and notes to distribution.
The present volume presents a detailed account of the taxonomy, biology and distribution of the European species of Siphonini. This group of tachinid Diptera totals 58 species in Europe of which 6 are here described as new to science. In most species, the immatures live as endoparasitolds of lepidopterous larvae, but a few species even attack tipulid larvae. Several species of Siphonini are of great economic interest as agents for the control of lepidopterous and tipulid pests in agriculture and forestry. An analysis and proposal on the systematic position of the Siphonini is given together with a key to larger taxonomic entities of Tachinidae. The generic classification is also critically emphasized. A separate chapter summarizes aspects of the group's natural history: life-cycles, mating behaviour, oviposition strategies, etc. The taxonomic part contains identification keys to genera and species, and for each species a diagnosis, a description and accounts on the nomenclature, biology and distribution is given. A separate catalogue details the provincial distribution of the 47 species occurring in Fennoscandia and Danmark. No less than 275 line drawings and 15 colour illustrations accompany the text.
