EASY PEASY BEESY

A cloudy day has given me a chance to catch up on myself a little after a lot of bee finding activity in last week's good weather. Although easter was early this year it does strike me as a lateish spring, although that may be anticipation on my part. Things are under way in east Gower as far as Oxwich but a visit to Overton yesterday showed me the west is still blasted from the winter, at least on the coastal strip. It was late enough to find my first Lesser whitethroat of the year diddling away at the top of Longhole Valley:

The main purpose of this post is to illustrate some of the bees which can be seen and identified in the field or from good photos. The first of these would be found in large numbers on the soft cliffs on the coast but also inland where suitable. Andrena flavipes (Yellow Legged Mining Bee) has brownish bands on the abdominal segments and a bright orange hind tibia in the females. Males swarm at the soft cliff and its slumped bottom part and emerge first (like many bee species). The females, not yet as common, collect pollen which can sometimes obscure the leg colour, as in this photo. Like many solitary bee species they also have a late summer generation.

Female

Another Andrena common in this habitat and on bare mud elsewhere is Andrena thoracica (Cliff Mining Bee) and, as you can see has a bare shiny black abdomen and bright orange thorax. It is also much larger than the Yellow Legged. Beware later in the season as there is a similar bee which has some white/pale hairs on the legs and abdomen. You are pretty clear at this time of year.

A third really easy bee is Andrena fulva (Tawny Mining Bee) which will be found everywhere with grassland/bare areas in which they nest, look for the excavation volcanoes on your lawn. Beware Lasioglossum calceatum will also do this a little later in the year.. It is also very common in gardens and will visit your fruit bushes. The males are not so easy to identify but the female is orange all over and easy to ID as long as you don't mix it up with some of the, much larger, bumble bees with a brown thorax.

This fourth bee, Andrena cineraria (Ashy Mining Bee), does not strike me as so common here but the reason I am looking is that I do not know for sure. I have found it a few times last week at Pennard, Caswell and last year at Rotherslade. 

One thing you might confuse with this is a worn or dark Melecta albifrons (Common Mourning Bee) which is a cleptoparasite of Anthophora bees and lays the egg in their nest whereupon the young hatch and eat all their food. If in doubt, as appearances of bees can vary quite a bit especially when old and worn, look at the wing veins shown in the photo below which can be seen in a good photo from the right angle.

Wing comparison:

If you are being guided by Steven Falk's excellent new bee book beware that the genera key says the vein indicated by the red line above goes to such and such a position on the second submarginal cell when it should be the third. Not rocket science, easy really!

This book will also help you identify from a good photo a lot of the cleptoparasitic Nomada bees which look like wasps. Here are two flying at the moment:

Nomada fabriciana (Fabricius' Nomad Bee) female, look at the red in the middle of the antennae, parasitises several Andrena but commonly bicolor and flavipes abundant on the coast here:

Nomada goodeniana (Gooden's Nomad Bee) male, again Andrena hosts including thoracica:

Note the shape, colour and position of the yellow spots on the thorax and abdomen. Not all Nomada are this easy though.

A sure sign of strong bee colonies are Bee Flies of the genus Bombylius and this discolor (Spotted Bee Fly) was a long way east, just west of Caswell.

These and other species such as Oil Beetles and Satellite Flies also take advantage of the bee's supplies to rear their own young at the Bee's expense. There is a lot of stealing within the bee/wasp group anyway, they are really interesting to study.

Much more information is available on the BWARS website which also has a link, under resources, to Steven Falk's Flickr pages with a huge mass of pictures and information:

Solitary bees

I will leave this here for anyone who does not get the BAY magazine and likes insects.

Sorry for posting here but am awaiting permission to post on a bird website.

Cwm Ivy Plantation yesterday:

10+ Crossbills very mobile no clear view.

First bees of the year yesterday at Mumbles Head Bombuses terrestris and hypnorum queens and this I take to be a Lasioglossum morio female:

ROLL ON SUMMER!

January Butterflies

A visit to Whiteford by Stuart Thomas, Micky Maher and I at the weekend (30/01/2016) resulted in relatively little in terms of birds (based on recent sightings).  The sea state was rough and it was difficult to scan offshore, and other than 1-2 great northern divers foraging in the shelter of the Burry Inlet (we didn't see two at once but the birds seemed relatively widely separated), a female merlin hunting across the saltmarsh, some nice mixed flocks of waders and small groups of eider and pintail, our efforts got a modest return.  There was no sign of snow bunting along the strandline or of slavonian grebes off the hide.

We were surprised to see some butterflies on the wing.  A red admiral was nice, but a painted lady was completely unexpected.  Both were basking among the dunes on the leeward side of the plantation, taking advantage of warm sunny patches.  The painted lady was extremely active and fresh, and eventually chased the red admiral over the canopy of an adjacent cypress (we had stopped to try and work out the species of cypress when we saw the butterflies).  As can be see from the photos the painted lady was fresh looking, while the red admiral was more faded and worn.

Having checked with the South East Wales Biological Records Centre, this is the third January record of painted lady for Glamorgan, so a bit of a better day than we thought.
