A mixed bag on a Sunday visit to Cranford Park

I was at Cranford Park at 10am Sunday morning and waited until 10.30 to complete my weekly UKBMS butterfly transect.
Not a great transect today. I expected to see more numbers but made do with 62 butterflies of ten different species during my 95 minute walk.
 
Todays tally....
62 butterflies / 10 species
 
Large White x 3
Green-veined White x 7
Small Copper x 1
Holly Blue x 4
Red Admiral x 10
Peacock x 3
Comma x 6
Speckled Wood x 15
Gatekeeper x 3
Meadow Brown x 10
 
Speckled Wood

Small Copper

Holly Blue

Red Admiral
The fine weather meant there were a few hoverflies around. The most prolific was the Volucella Zonaria and they were dotted all around the park in various habitats and great numbers....

Myathropa florea - male
Just as I was nearing the end of my transect, on a section that runs parallel between the A312 and the River Crane a large dragonfly emerged from the reeds by the stagnant pond and landed right in front of me. It had recently emerged and was still fluttering it's wings drying them off.
 
It was a lovely male Common Hawker with the most amazing colours....
 


 
On the way out of the park I also saw another Common hawker, but it was a way off and quite camouflaged against an old buddleia flower stalk.....

 
The water level on the river had dropped considerably since last weekend.....
 
 
Again the warm wet weather this week provided ideal conditions for some more fruiting fungi. This time I found two very good sized Puffballs, the largest was the size of a football....

 
In the meadows I found two juvenile Kestrels still loitering and honing their hunting and flying skills...


 
In Cranford Woods there was the unmistakable call of a Sparrowhawk, followed by several more calls which led me to stand under a dead tree and look up to see this juvenile......
 

 
Following it's progress it inadvertently led me to directly to the nest where there were two more juveniles perched in the branches. Sadly trying to get photos were near on impossible but I did manage to witness a food pass between one of the adults and juveniles, and then one of the young perched very briefly out in the open......




 
before flying off to land in another high tree and start the process of continuous calling all over again.
Apologies for the dreadful photos, I blame the fact I had the wrong lens on my camera.
 
Last weekend I reported that I had found three chrysalises down the alley way from Roseville Road. I stated they were Small Tortoiseshell when in fact they are Comma. Today I found another two in exactly the same place.
 
Comma chrysalis - probably due to emerge this week

and my new mystery chrysalis - awaiting identification
So a proper mixed bag from Cranford Park today. Butterflies, hoverflies, hawkers, juvenile birds of prey and fungi. Just what every Country Park should contain.
 
 
 
 
 

Off the beaten track at Maple Lodge NR

 
Saturday I was at Maple Lodge in the company of Martin Parr and Emily Hobson. Emily and I were being treated to an 'off piste' insect experience by Martin, and apart from one short sharp rain shower the weather stayed relatively good.
 
Most of the visit was spent exploring the wetland meadow in front of the Rotunda Hide. The high-light for me was seeing not one, but two very good sized female Wasp Spiders. I've seen these before at Harefield, Rainham and Barnes. But I've never seen them as big as the ones at Maple Lodge. And previously I've only been able to photograph the top of the spiders. Today however I got some cracking views of the underneath. The web has a wide, white zig-zag strip running down the middle, known as a 'stabilimentum', the function of which is unclear. Mating is a dangerous game for the small brown drab males; they wait at the edge of the web until the female has moulted into a mature form, then take advantage of her jaws being soft and rush in to mate. However, many males still get eaten during this time.
 




The one below is the same female as above, but photographed again after the rain....
 

 
The other large female was fairly nearby but lower down in the grass so I couldn't manage a full framed shot. But I did get some nice close ups of the colourfully marked abdomen....


 
Of course there were some butterflies, not in great numbers as the weather was a little breezy and chilly....
 
Comma

Large White

Peacock
The brambles and nettle patches were attracting a few hoverfly species, the two most prolific being the ones below.....
Helophilus pendulus

Myathropa florea

Hoverfly species pupa
Naturally there were plenty of bugs to keep us all entertained.

3rd instar Southern Green Shieldbug
 My Grasshopper and Cricket identification skills are not that great despite having a great field reference book, so the ids underneath each photo below may be incorrect....
Long-winged Conehead

Emily has eyes like an eagle. She spotted this wonderfully weird critter below in the shallow waters edge...

She also found a couple of 'mud bugs' which may be first records for the Nature Reserve. Unfortunately my photos of the 'mud bugs' aren't clear enough to post.
 
I'm still trying to get these below identified. I walked past them initially thinking they were hoverfly pupae but I'm now wondering if they are ladybird pupae with a possible fungal parasite ?
 

 
The day was completed with a wonderful sighting of a young Grass Snake which sadly my camera couldn't focus on before it slid off.
 
A great afternoon with two insect experts and lots of chances for macro photography.
Thank you Martin for escorting us 'off piste' and thank you Emily for your outstanding knowledge.
