Lady Lemon - _TNY_1387 (In Explore 11/1 2025)
The brimstone butterfly (Gonepteryx rhamni) is an easibly identifiable species in many European countries - something that is helped by it having a very long flight season
What most aren't aware of however is that it is a species where it is easy to tell if which sex it is.
The girls have a more pale green colour like this one on a heartleaf oxeye (Telekia speciosa) while the guys instead have a warmer yellow hue (like this: www.flickr.com/photos/tinyturtle/52772819322/)
