Greater Knapweed - Centaurea scabies is big and showy, like a cross between a cornflower and a thistle, with whiskery petals in a whorl. It is a valuable nectar source for insects and a favourite flower of butterflies, including the Marbled White and Dark Green Fritillary. It also has therapeutic properties, and was once used in skin ointments to heal wounds and infections. Centaurea scabiosa is a truly outstanding wild flower which outshines many cultivated plants.
A bee balances two water droplets on its back as it perches on a flower. The picture was taken by keen photographer Agus Sudarmanto near Doha, Qatar. He said: "There is no rain at all here so we have to spray water periodically on flowers. This is the reason there were drops on the bee, but it was amazing how it was just delicately balanced on his back."
¿Sabías que las abejas están desapareciendo? La polinización de las flores es vital para nuestra alimentación y para la biodiversidad, pero las abejas encargadas de esta misión peligran. Entre otros factores, mueren por la agricultura industrial y su uso de plaguicidas tóxicos. Seamos conscientes y pongamos nuestro granito de arena.
