Spring 2020 Solitary Bees


It's been a while, but with coronavirus rampant and time on my hands, I've been finding lots of new stuff in the garden.

Hairy-footed Flower Bee male
First up, but not new to the garden, just the first time I've managed to get a good photo of a male hairy-footed flower bee (Anthophora plumipes).  The male gives the species its name and is normally found darting about guarding or trying to mate with the females.  I don't understand the term 'flower bee' because it is  actually a mining bee, and all bees forage on flowers.  I guess it may be to distinguish them from the Andrena species.



The chocolate mining bee (Andrena scotica) - named for its colour rather than its diet, is a fairly plain brown bee with little else to distinguish it from other solitary bee species.  I thought this female was a Buffish Mining Bee (A. nigroaenea) going by the longish hair and buffish colour, but it has been identified as A. scotica.  It has a two-toned scopa (hind leg where the pollen goes) whereas the A. nigroaenea would have had an orange one.

This male Chocolate mining bee is carrying some mud on the back of his thorax which probably came from the hole he was born in.

The female tawny mining bee (Andrena fulva) is not a new species and is a common species, I've just never had such a clear shot before.  It is resting on Pieris, a great plant for early spring forage for a range of species.

The red mason bee (Osmia bicornis) is a regular resident in our bee hotels and emerges slightly later than the Andrena species shown above.

I was actually putting up a new bee hotel and one female was investigating the holes even before I had it screwed together and on the wall.




































One group of solitary bees that is not welcome in the bee hotels, at least as far as the residents are concerned, are the nomad bees.  They are not welcome because they are cuckoo bees and will lay their eggs alongside those of their unwitting host, which when it hatches will eat the egg or larva of the host.  They are a difficult group to identify, but I've managed to sort out identification for two of the common ones shown here.

Gooden's Nomad Bee (Nomada goodeniana)











































The Blackthorn Mining Bee (Andrena varians) was a new species for the garden, as was Trimmer's Mining Bee (Andrena trimmerana).  Perhaps if I spend more time searching out new species, identification will get easier, but then again...

Birds - the bike list

The only strenuous exercise I can get during the Covid-19 lock-down is to ride my bike.  As birds are a bit more conspicuous now that there are fewer people about, I thought it would be amusing to play the twitcher and compile a 'bike list'.  The rules are - no binoculars (which would have been impossible anyway) and no stopping to identify anything and heard birds count.  They have to be identified on the move. Stopping to identify a bird and then riding on while keeping the same bird in sight would be cheating! That means that this list is full of easily identifiable birds but it's a reasonable length under the circumstances.

So, in no particular order -

  1. Blackbird
  2. House Sparrow
  3. Great tit
  4. Linnet
  5. Magpie
  6. Carrion Crow
  7. Rook
  8. Jackdaw

  10. Avocet
  11. Mallard
  12. Shoveller
  13. Pochard
  14. Widgeon
  15. Tufted Duck
  16. Moorhen
  17. Coot
  18. Canada Goose
  19. Greylag Goose
  20. Cormorant (Male with white thigh spot in full view)
  21. Herring Gull
  22. Black-headed Gull
  23. Chiff-chaff (Heard)
  24. Little Egret
  25. Great White Egret
  26. Redshank
  27. Marsh Harrier
  28. Common Buzzard
  29. Kestrel
  30. Gadwall
  31. Starling
  32. Wren (Heard)
  33. Ringed Plover
  34. Mute Swan
  35. Collared Dove
  36. Stock Dove

  40. Robin
  41. Pied Wagtail
  42. Oystercatcher
  43. Dunnock
