In spring we can see yellow as well as white butterflies flying. Despite the seemingly great difference in colour we have to do with the same species – the brimstone butterfly.
The difference in colour is related to the sex of the butterfly – male brimstones are dark yellow, heralding a sunny and warm summer.
