Colourful Dutch beetles, new book

This video from North Dakota in the USA is called Thistle Tortoise Beetle (Chrysomelidae: Cassida rubiginosa) on leaf.

Dutch entomologist Jaap Winkelman has published a new book. It is available here.

The name of the book is De Nederlandse Goudhaantjes. The word goudhaantje in the title stands for two small bird species living in the Netherlands, goldcrest and firecrest (‘vuurgoudhaantje’).

However, Winkelman’s book is not about birds. As goudhaantje is also the name of a family of mainly colourful beetles, Chrysomelidae or leaf beetles. There are over 35,000 leaf beetle species, according to Wikipedia. About 38,000, according to Winkelman’s book. Of these, 59 species live, or have lived in earlier times, in the Netherlands.

With Winkelman’s book, people will be able to discover all Chrysomelidae of Belgium and the Netherlands.

This video is called Scarlet lily beetle (Lilioceris lilii); a leaf beetle species living in the Netherlands.
