Over fifty species of butterflies live in the city

The first citizen observation of urban butterflies has found fifty-one species living in Barcelona, 22% of the total number of recorded species in Spain. The goal is to discover the behaviour and patterns among these invertebrates to be able to protect them.

The field work was conducted by 35 volunteers, who observed 3,636 butterflies between March and September 2018, the strongest presence being in June.

The most abundant species is the cabbage white, while other species include the common yellow swallowtail and the scarce swallowtail, with bright markings and colours on their wings.

The location of species can be found on the collaborative map produced by the observation exercise.

The observation continues in 2019

The butterfly monitoring exercise was carried out simultaneously in Madrid, with very similar resources and results as Barcelona.

The observation is to continue this year with a broader network of volunteers to gain more in-depth knowledge of the butterflies which live in the city and which green areas they proliferate in, to be able to protect urban biodiversity.

The citizen observation of urban butterflies is an initiative by the Centre de Recerca Ecològica i Aplicacions Forestals (CREAF) in collaboration with the Museu de Ciències Naturals de Granollers, the Universidad Complutense de Madrid and the Universidad Autónoma de Madrid.
