In this field guide, we describe eight families of flies that have three pulvilli on their feet (tarsi) as a common characteristic. These are older and closely related families of flies (Homeodactyla). More than 150 species are described, from ‘irritating’ Horseflies to brightly coloured Soldierflies, from slender Awl-flies to tiny Hunchback flies and from stocky Odour-flies to slender-legged Snipeflies. Species texts offer short information on occurrence, flight season and rarity. Clear photographs support the texts.
Species can be identified as much as possible from field characteristics or photographs. Keys are supported by functional drawings which clearly illustrate the characteristics. Characteristics which can be seen only in living specimens, such as eye colour, are used as much as possible. In that way, this guide is useful for both nature lovers and beginning and expert entomologists.
Theo and André together published an earlier digital field guide to Horseflies (Veldgids Dazen) on Waarneming.nl. The content of the digital guide on horseflies has been integrated in its entirety in this field guide.
