Ragweed Leaf Beetle
A brown beetle with dark longitudinal stripes on the elytra, introduced to several countries as a biocontrol agent against common ragweed. Both adults and larvae feed on ragweed foliage.
Did You Know?
It was introduced from North America to the former Soviet Union in the 1970s as biological control against ragweed, a major hay fever allergen source.
Smooth Hister Beetle
A compact, highly polished black beetle with fine elytral striations. It is one of the most common dung-dwelling hister beetles in Europe.
