Cuckoos have left the UK, yet cuckoos remain.

Cuckoos, parasitic birds of reed warblers and other host birds, may have left the UK for their African winter quarters, yet cuckoos remain.  Cuckoo bumblebees, that is, which can commonly be seen in gardens.

Buddleia or butterfly bushes are visited not just by butterflies but also by bees.

Buff-tailed bumblebees
For example, here are a couple of Buff-tailed bumblebees, Bombus terrestris.  The larger, with a buff coloured tail is a queen.  The smaller, with a white abdominal tip is a worker or a male.

Queens produced in late summer are fertilised and hibernate over winter until next spring when they start a new colony.  All the other bees in the nest die.  (Although with milder weather in the south, some nests may survive the winter.)
Southern Cuckoo bee
On this same bush yesterday in my West Sussex garden was a Southern cuckoo bee, Bombus vestalis, which is a parasite of Buff-tailed bumblebees.

Just like the cuckoo bird, cuckoo bumblebees lay their eggs in a host bee's nest, which is cuckolded into rearing the cuckoo bee's progeny.

Bumblebees and honey bees are vital pollinators of plants.  Solitary bees play an even greater role.  

Advice for gardeners wishing to maintain a bee-friendly garden is avaiable from the Bumblebee Conservation Trust at https://bumblebeeconservation.org/get-involved/gardening-for-bees/


"The extraordinary lives of wild bees and the important role of gardeners in their survival" is one of my talks on natural history, details of which are at http://www.peterlovetttalks.co.uk/page15.html

Six Dragonfly and Damselfly species in the Sussex High Weald yesterday.

 A perfect location for White-legged damselflies, which although uncommon, were numerous here yesterday.

Southern Hawker Dragonfly newly emerged at Old Lodge, nature reserve, Ashdown forest, yesterday


 There is something hanging from the bracing strut under the bridge.
 It looks like a newly emerged Southern Hawker Dragonfly, Aeshna cyanea

This was at 13.00hr.

 I went back later at 15.00hr to see how it was getting on.

I had to kneel on the bridge and hold my camera over the water without dropping it.
It was quite dark and the shutter speed was too slow for a sharp image on close-up macro mode.  A flash was used to get these shots.
