From 6 till 28th of July 2019 people in the Netherlands were asked to record the number of butterflies in their garden for 15 minutes. In total 73.445 butterflies were recorded in 2956 gardens. This gives insight in an important habitat that is not easily accessible for professional researchers. One of the outcomes is that in large parts of the Netherlands the Small Tortoiseshell, a classic garden butterfly is now rare in gardens in the south and east. This is possibly a result of the drought in 2018.
