Tuesday 1st, Saturday 5th & Sunday 6th August

Tuesday 1st August 2017:
I started today's visit at the Wilden Top car park and on walking the footpath along the eastern edge of the Common I picked up on 13 Greenfinch (4 adult & 9 juveniles) feeding in the adjacent paddock, a  good sign that they have successfully bred locally.  Also present in the paddock were 3 Pied Wagtails (1 adult ♂ and 2 juveniles).

It was quite a dull overcast day and not particularly productive on the invert front although I did record a single Red Admiral.  What was interesting however was to see and photograph a Kite-tailed Robberfly perched with it's hoverfly prey.   The species gets it's name from the projecting tab on the last segment which bears a tuft of black hairs.  This tab is normally forked and resembles a kite's tail.

Saturday 5th August 2017:
Today I undertook another walk around the Lower Heath side of the Common.  I arrived at the site early afternoon as the skies had started to clear following the morning's showers.  In one area of nettles I walked through I flushed 3 Mother of Pearl moths.  Interestingly, nettle is the food plant of the larvae of Mother of Pearl.  I also observed a single Common Carpet moth.  Butterflies noted during this visit included 1♂ Common Blue, 2 Small Copper and 2 Small Heath.

As the summer draws on there is more fungi appearing on the Common with 3 Parasol Mushroom and a Mosaic Puffball noted during today's visit.

On the bird front it was nice to hear (and then see) a flyover Yellow Wagtail that was heading ENE.

Sunday 6th August 2017:
I only had time for a brief visit to the Lower Heath section of the Common today but was rewarded with another species of  robberfly for my site year list in the shape of a Brown Heath Robberfly.  This is now the third species of robberfly that I've recorded at the site alongside Fan-bristled and Kite-tailed robberflies.

As sunshine and showers were the order of the day weather wise, I decided to take advantage of a sunny spell and check the thistle flowers in at the lower terrace area of the Common to record what may be feeding on them.  It proved a good move as I actually recorded a stunning ♀ Pantaloon Bee on one flower head and a ♂ Pantaloon Bee on another.  With this species it's definitely the female who wears the trousers!

From the lower terrace I headed over to the SE side of the Common and undertook a walk/mooch from Lower poolands car park.  On arrival at the parking area I picked up on a Flesh Fly that was perched on the fence.

Flesh Fly (Sarcophaga sp.)
















The walk itself was quite productive as I observed a basking Common Lizard and recorded 2 Brown Hawker dragonflies, a Southern Hawker and a ♂ Common Blue butterfly.  The highlight though (other than the lizard which are always a pleasure to see if they don't scurry off into the undergrowth) was a diminutive 22-spot Ladybird.  This is the first I have recorded at the site this year.

As well as the wonderful array of inverts it was a good day for Oak galls as I added three more species to my site year list in Common Spangle Gall, Knopper Gall and best of all Ramshorn Gall.  the latter being a species that was formerly scarce but appears to be on the increase in the county.  Ramshorn Galls are are produced on the buds of oak trees by the wasp species Andricus aries.  This species was first recorded in the UK in 1997 and in Worcestershire in 2013.

Towards the end of my amble around I recorded a rather stunning ♀ Meadow Grasshopper with a lovely pink and green colour form.

Wednesday 26th & Sunday 30th July

Wednesday 26th July 2017:
I only had time for a brief visit to the Common today so I just walked a short circuit near the Wilden Top carpark.  There wasn't much of note except for a couple of Linnets and a rather showy singing Yellowhammer.  I can honestly say that I never tire of hearing/seeing these stunning arable birds!

Yellowhammer (Emberiza citrinella)
















I then headed over to the SE side of the Common for a quick mooch around the Oak woodland, where I discovered a rather nice clump of young Beefsteak Fungus that was exuding its blood like juices

Beefsteak Fungus (Fistulina hepatica)
















Sunday 30th July 2017:
Another sunny, mild day saw me pay a visit to the Lower Heath area of the Common.  The first thing that struck me was seeing a flurry of activity around the now flowering Ling heather.  On close inspection I soon picked up on good numbers of Heather Colletes feeding on them.  Heather Colletes is a rather attractive  solitary mining bee that times it's emergance to coincide with the flowering of the heather.  It is quite a small bee (smaller than Honey Bee) with a very prominant stripes/bands around it's abdomen.

Heather Colletes (Colletes succinctus)
































Butterflies of note during the visit were as single Red Admiral and 4 Small Heath.  Good numbers of Gatekeeper were still present with some seen feeding on the Ling flowers.

Tuesday 25th July 2017:
It was another hot and sunny day on the Common (weather that seems like a distant memory as I type this post) and I decided to start my visit by checking out the thistle flowers at the lower terrace.

A number of Leafcutter Bees were visiting the flowers and from the photos I have taken I've managed to ID the species as Wood-carving Leaf-cutter (Megachile ligniseca).  One of the key identifying factors of this species are the graded colours of the scopa (the hairs on the underside of the abdomen that are used for carrying pollen)

Notable butterflies seen during the visit were 1 Marbled White, 2 ♂ Common Blue, 1 ♂ Brown Argus, 2 Small Copper and 1 Red Admiral.

Brown Argus (Aricia agestis)
















During my walk I also discovered a Reticularia lycoperdon slime mold.  This white globular mass that can be found on dead wood isn't actually a fungus.  One of it's common names is the False Puffball due to the similarity in shape and the fact that it eventually splits open releasing a mass of brown spores.

My final stop on the walk was at Rush Pool which sadly has now dried out to all but a 10ft by 6ft area of shallow water.  That said there were good numbers of Common Darter dragonflies here including three oviposting (egg-laying) pairs.

Saturday 22nd July 2017:
A visit to the lower terrace of the Common gave the opportunity to observe a number of  bee species visiting the numerous thistle flowers.  Although the majority of which were Red-tailed Bumblebee,  I was treated to good views of a slightly faded Vestal Cuckoo Bee

Vestal Cuckoo Bees are kleptoparasites of the Buff-tailed Bumblebee (Bombus terrestris).  The female cuckoo bee will enter the Bombus terrisitris nest and kill the queen.  She will then lay her own eggs to be reared by the Bombus terrestris workers.

Of interest during the visit were a small number of  Leafcutter Bees (Megachilie sp.) that were visiting the thistles.  

A Field Grasshopper was also recorded.  This individual was of a different colour form to the one shown in my previous blog post.

It was a hot, sunny day on the Common and I decided to pay a visit to the Lower Heath (the west side of the Worcester Road).  It proved a worthwhile decision as, shortly after arriving, i picked up on a stunning Brown Argus visiting the Ling flowers not far from Cooks Garden Centre.  This was especially pleasing as it is the first Brown Argus i have recorded at the Common this year.

Other notable butterflies observed today included 1 ♂ Common Blue, 2 Marbled Whites and 2 Small Copper.  I also found a Eudemis profundana micro moth at rest on an Oak leaf.

I also discovered a young Oak Cherry Gall on the underside of one of the Oak leaves.  This gall will often turn a reddish colour as it matures hence the common name.  It is caused by the tiny gall wasp Cynips quercusfolii.  Interestingly, these galls tend to be smooth when formed on the leaves of English Oaks but warty when formed on the leaves of Sessile Oaks.

One thing that did really strike me on today's visit to the Common was the sound.  Due to the heat and the time of year the multitudes of Broom seed pods were bursting open in a cacophony of sound.  It sounded like I was walking around in a giant bowl of Rice Krispies with all that snap, crackle and pop going on!

From the Lower Heath I crossed over the Worcester Road to check out the former carpark area.  Here there were 2 ♂ Beewolf, a Comma and a brown form Field Grasshopper present.  Also observed at this location was a Small Copper butterfly that was feeding on the Yarrow flowers.

Thursday 13th July & Saturday 15th July

Thursday 13th July 2017:
This afternoon I visited Hillditch Pool.  The weather was cloudy with sunny spells but it still felt mild despite the slight breeze.  The highlights of the visit came on the bird front when a ♀ Kestrel was wheeling about overhead training 2 juveniles.  Also great to see was the Kingfisher that passed through following Titton Brook.

There were only 2 dragonfly species active there today with 3 Brown Hawker and 1 Emperor noted. On the damselfly front I observed Azure, Banded Demoiselle, Blue-tailed, Common Blue and Red-eyed.

The following butterflies were noted:  2 Comma, 1 Small Skipper, 2 Speckled Wood, 1 Large White, 1 Small WhiteGatekeeper, Meadow Brown and Ringlet were still fairly abundant.

Both Meadow Grasshopper and Speckled Bush Cricket were observed during  the visit.

A brief visit to the west side of the Common today produced my first immature Common Darter dragonfly of the year at the site.

On the Knapweed flowers I found an absolutely stunning ♂ Pantaloon Bee (they are also known as the Hairy-legged Mining Bee). These are so called as the female of the species literally has big, fluffy hairs that cover her legs which resemble pantaloons.  They use these hairy legs to brush the sand out of nest burrows.   The males on the other hand don't 'wear the trousers' so to speak and do not have such pantaloons on their rear legs, although they are still quite hairy, distinctive looking bees in their own right. 

An image of a female Pantaloon Bee can be viewed at the following link:  https://www.hartleburycommon.org.uk/linked/dasypoda%20hirtipes,%20hartlebury%20common.jpg

Mooching around in the grasses near the Knapweed I discovered a few spent larval cases of the Burnet moths.

Butterfly highlights included 2 Small Coppers that were feeding on the flowers of Yarrow

Also of note were 2 Swifts that flew over heading SW.
