Burnets (Zygaenidae) are diurnal moths of which only a few species occur in Europe. These butterflies are poisonous due to the presence of hydrocyanic acid and therefore have a bad taste for enemies, such as birds, bats and spiders. The antennae are often toothed or club-shaped. The adult butterflies vary in size and have a well-developed tongue and often visit flowers for nectar. The wings vary widely in shape and are often metallic in color. The Zygaenidae have two subfamilies for which I spotted specimens, the Zygaeninae (drops of blood) and the Procridinae (metal butterflies).
Subfamily: Procridinae
Genus: Adscita
The Forester – 2019 (NL)
(NCBI-index: 753147)
The most common type of metal butterflies in the Netherlands is the Forester (Adscita statices). The forewing is metallic green, sometimes bluish, and the hindwing is light brown-grey. The abdomen is red or green with a metallic sheen. Here the Forester differs from the Blackthorn Aurora Moth (Rhagades pruni) which has a black abdomen. The male has slightly larger, wider and more sprung antennae than the female. The flying period is in one generation from mid-May to early August. Host plant: Sorrel. Dutch name: Metaalvlinder. Frisian name: Metal flinter.

Six-spot Burnet – 2016 (NL)
(NCBI-index: 287375)
The Six-spot Burnet (Zygaena filipendulae) is a butterfly with six red spots on the forewing. The red spot at the base is separated by a vein and care must be taken for identification. Rarely, the red color is replaced by yellow. The ground color of this butterfly is blue-grey. The flight time is in one generation from May to September. He flies with a usually slow buzzing flight during sunshine and is mainly attracted to a range of flowers including thistles. Host plant: Common Clover, Bird’s-foot and Trefoil. Dutch name: Sint-jansvlinder. Frisian name: Sint-jansflinter.
