South of Marston Thrift

Windy conditions south of Marston Thrift were a challenge for macro photography with its narrow depth of field, but at least things weren't flying around too much in the overcast cool weather. My flash was also on the blink (every pun intended) only firing when it felt like it!

Slow Worm

Found this male slow worm hunting at Rowney Warren this afternoon. It didn't find anything to eat while I was watching and it eventually disappeared into the undergrowth.

Push me pull you

A pair of Bee Flies (Bombylius major) flying (one of them backwards!) at Old Warden Tunnel today.

Cooper's Hill

A few sightings from a blowy day on Cooper's Hill:

The gorgeously-coloured female Andrena fulva. You may find these nesting in holes in soil or lawn in your garden.

Female spider-hunting wasp Anoplius viaticus which overwinters as an adult, hence is one of the earliest solitary wasps to be seen each year:

The spectacular Green Tiger Beetle (Cicindela campestris), always on the lookout for a snack.

An early species of micro moth Dyseriocrania subpurpurella (assuming I have the ID right) which develops on oak, here hanging tightly to heather in the wind.

Early Purple Orchid

It's not too early to look for Early Purple Orchids. Here's a rosette I found today in a wood where I saw them flowering last spring...

Bronze Shieldbug - A quick change of clothes

A final instar Bronze Shieldbug Troilus luridus nymph was sitting on a willow leaf at Priory CP on Sunday, so I brought it home to take a better picture. Two days later it is now an adult and looking considerably different! (It still has the final segment of the right antenna missing though). I'll take it back to Priory tomorrow when I go to work.

Macrosiphoniella millefolii

What may be a county-first according to Alan Outen, Macrosiphoniella millefolii feeding on Yarrow. Found near Roxton on 17th August 2014

Wasp Spider season

It's Wasp Spider season again. This one was at Sandy Smith NR yesterday.

Terellia longicauda

Worth looking around the flowers of Woolly Thistles for the distinctive fly Terellia longicauda which lays its eggs in the head, here at Mowsbury Hill. (longicauda translates roughly as "long tail"). Alan Outen thinks may be a first county record.

Here's a hopeful male hangling around too:

Palomena prasina?

On an oak leaf near Wilstead I spotted this clutch of eggs on 14th July. Bernard and Sheila suspect they may be Palomena prasina the Green Shieldbug.

On 20th July this is how they look now. Can't help but call them "minions"! (Created from a photo stack using CombineZP).

Glad I photographed them when I did because only about 6 hours later this is how they looked:

And nearly 20 hours later they are now in a huddle. No idea why they are doing this rather than feeding. Maybe time will tell. (Yes they are still alive as I've gently prodded a couple).

(I've now googled this behaviour and found this link which suggests they may do this until they turn into 2nd instar which may take a week or more).

Odynerus spinipes

This female Odynerus spinipes wasp was busily provisioning her nest today at Sandy Smith NR. Like most species of solitary wasps this one has a very narrow view of what it considers suitable food for its young, in this case, weevil larvae. The nest cavities are inside the soil behind the vertical face on the left but this genus (Odynerus) builds an elaborate curved chimney over the entrance hole but we aren't sure why as other genera manage perfectly well without one. There must be some advantage to justify the expenditure of time and energy required to make it.

Speckled Wood life-cycle

A butterfly fluttering around its larval foodplant is always worth watching to see if it is a female looking to lay eggs. At Mowsbury Hill LNR on 26th April a female Speckled Wood (with larger light patches than males) was hopping from plant to plant at ground level. After she moved off one patch of grass I looked for an egg and it was easy to find on a blade of grass. It appeared to the eye rather whiter than it appears in this photo. About the size of a grain of salt it's amazing to think this was manufactured inside a butterfly and will itself become a butterfly in a few months, the second of probably three broods this year.

On 5th May this was the newly-hatched 1st instar larva, about 3mm long:

On 7th May it is now a 2nd instar larva and about 1mm longer:

Having now travelled to Dorest and back with me(!) it has surprised me by pupating overnight (23rd-24th May). The caterpillar seemed much too small and the pupa is tiny, only 12mm from end to end! I have my fears that it may have been infected by something - time will tell. Here's the newly formed pupa with two white features of "something" inside.

Much to my surprise the pupa seems to have progressed normally and is nearly ready to emerge (3rd June):

And the final product, released at Mowsbury Hill (3rd June) within a few metres of where the egg was laid 38 days earlier. I'm astonished that a normal-sized speckled wood could emerge from a pupa that seemed about the right size for a small heath, and that it could transform from a caterpillar to a butterfly in only 11 days. I'm glad that I still find some things wonderful!
