The garden March 2022

It was actually the 26 February that I saw my first male Osmia cornuta.

It was not until 19 March that I saw the first female. She reminds me a bit of Winnie the Poo trying to get into Rabbit’s hole. She is much more substantially built than her mate and he has had to wait a long time for her to hatch out, as usual.

She gets straight onto the task of laying eggs and providing each one with enough stores of pollen to grow into a new bee. She goes in head first with her load of pollen neatly attached to her hairy abdomen and then comes out after she has pressed the pollen in place with her head, still with the pollen grains adhering to her.

I have not seen as many of these bees as in previous years.

Kourosh discovered a suspect tiny hill of soil just outside our front door and marked it for me with some twigs. As I passed by this morning, I noticed the soil quiver – just as I had seen molehills move on occasion.

The hole is completely covered in the evening so I quickly rushed in for my camera and sat to wait. I was rewarded by the appearance of this little head. After a few tentative ups and downs, she eventually flew out.

I think she might be an Andrena fulva. I usually see her later on the raspberries so I would be interested in what she favours at the moment. I will keep my eyes open for her now.

We have discovered another bulb worth planting in pots to attract the bees. Puschkinia are like mini Hyacinth but their flowers are more open for the bees. In addition they are gently perfumed. I find them a little small and pallid but if you like to attract pollinators to your patio you might like to try them.

All the bees have a huge amount of pollen to choose from at this time. The Willow is just about finished but the woods are full of white Sloe blossom. Gardens are full of flowering fruit trees and our honeybees are working hard bringing in the pollen.

Check out this video (16 secs.) to see the different colours of pollen they are bringing in https://youtu.be/nX3C_QTvvYM. And now HERE is the correctly posted video. Thank you Ann and Julian :).

The bees in February

This winter has been mild with just one spell of exceptionally cold weather.  The overnight temperatures dropped to sub-zero even down to minus eight degrees centigrade, but that all finished a week ago only to be replaced by exceptionally warm, sunny weather with highs of plus eighteen and mild overnight temperatures!

The quick seesaw of temperatures has not disturbed our honey bees who are as active as ever gathering pollen and nectar.  I like to try and guess where the pollen comes from by its colour.  The above photograph does not show a darker more red pollen that is somewhat rarer.

The pale cream pollen might come from the Viburnum tinus as there is a large bush not far from the hives that is in flower now.

However, judging on noise level the Hellebores in the garden are preferred over the V. tinus and the pale pollen could be theirs.

I’ve no doubt that the majority of the pale yellow comes from the winter flowering honeysuckle.  I now have three bushes in the garden and the largest is very close to the hives.

The darker red yellow I would guess comes from the abundant gorse around the garden and some dark yellow from the Lamium.

The small flowers of Veronica (I think persica) have opened all over the garden and surrounding fields in the past few days.  Some fields are covered by a blue haze of these flowers.  Although tiny, they provide both nectar and white pollen to honey bees from what I have observed.

It is not only the honey bees that are attracted to the Veronica.

I did not expect to see any solitary bees (with the exception of bumble bees) in the middle of February but this one is getting off to an early start.

The appearance of the Syrphid flies is not so unexpected as there are plenty of Lesser Cellandine (Ficaria verna) around but I rarely see bees on the Cellandine.

We try to provide different sources of water for the bees.  This mossy stone is a favourite place for them.

Once the sun hits the stone warming up the damp moss there will be five or six bees sunning themselves and taking water.

What surprises me more is the number of bees on the ground taking water off leaves.  They are particularly partial to these leaves.  Perhaps the humidity pools in convenient sized droplets or perhaps they are taking in more than just water from the surface of the leaves.

Yesterday I saw Bombus pratorum queens for the first time.  There were three or four in the large winter honeysuckle bush.  They move much more rapidly than the ponderous Bombus terrestris queens that fly all the winter in the good days.  All were stocking up on nectar but I have not seen any of the bumble bees gathering pollen yet.

The carpenters (Xylocopa violacea) have returned in earnest this past week and join the melee in the honeysuckle.  In the melee I am sure I saw an Osmia cornuta.  The red body is difficult to miss but it was soon gone and I was unable to take a photograph.

Stop Press!  I have just seen a Bombus lapidarius today but she seemed badly infected by mites.

Close up the mites resemble ticks.  They have taken hold in the softer, less protected folds of her body and do not look at all comfortable.  Some of the mites which infect solitary bees live on the cell debris of the nest and have little effect on the life of the bees but I am not so sure about these ones.

The bee season is off to an early start in the garden.
