small copper (Lycaena phlaeas) Portsdown Hill, Compartment 1

Three small copper were recorded in Compartment 1 on 29th July 2014 (week 18 transect) - bringing the current butterfly spp total to 25 recorded spp across Comp 1 & 2 this year.

Although having returned from a weekend in Dorset - I was gripped to see a report of Queen of Spain
fritillary (Issoria lathonia) seen below Fort Southwick on the 26th July 2014, the record reported on:

Today, I caught up with John Goodspeed - who runs the website, and he knows the reporter and was satisfied with their account of the species. This is a very exciting record - and it will certainly keep me on my toes for the next couple of visits.

blues and brown blues Portsdown Hill Compartment 1

I was almost / I was (?) caught out this morning, undertaking the transect in Compartments 1 and 2 when a new butterfly species appeared on the wing.

Expecting small blue (Cupido minimus) - as per the last transect - I watched as a small flashing silver blue / brown butterfly launched an airborne assault on a passing common blue (Polyommatus coridon) - plucky small blue - I thought. And then it landed, and I stalled as the underwing was completely wrong - resembling superficially at best a small female common blue?

Hasty photographs were taken and I consulted Richard Lewington, (2003) "Pocket Guide to the butterflies of Great Britain and Ireland", British Wildlife Publishing.

".. specimens are best confirmed from the underside, where the lack of a spot in the cell of the forewing, near the body, and the almost vertical twin spots on the top edge of the hindwing are conclusive." (Lewington, R. 2003)

I found that the noticeable lack of spot on the forewing was very obvious - but the almost vertical twin spots on the hindwing, were very subjective in the photo given the angle of the wings at rest. Still I was pretty sure that I had now successfully recorded brown argus (Aricia agestis).

A second similar individual was also seen, and small blue were also seen in flight alongside them.

The record was later confirmed when I submitted the photo to scrutiny on the "Butterfly Conservation in Hampshire" FB page.

This record is the 24th butterfly species that I have recorded in Compartments 1 and 2 so far in 2014, and the 25th (possibly 26th) that I have recorded on the whole of the hill this year.

Alice Holt and Thursley Common

Out of county trip today, saw David and I heading for the Surrey heathlands in search of Lepidoptera and Odanata.

At Goose Green, Alice Holt, we watched purple emperor (Apatura iris) - with one male atop a sweet chestnut (Castanea sativa)- tussling a second male on the wing; and purple hairstreak (Neozephyrus quercus) - both species lifers for me.

Also flying ringlet (Aphantopus hyperantus), peacock (Inachis io), meadow brown (Manilio jurtina), large skipper (Ochlodes venata), marbled white (Melanargia galathea), gatekeeper (Pyronia tithonis) and silver-washed fritillary (Argynnis paphia).

Odanata interest was provided by brown hawker (Aeshna grandis) and southern hawker (Aeshna cyanea).

A goshawk (Accipiter gentilis) overhead was a complete bonus!

At Moats Pond, Thursley Common in the afternoon - we counted 14 species of Odanata from pond-side and boardwalks - including two more lifers for me: black darter (Sympetrum danae) and downy emerald (Cordulia aenea).

mid July update from Portsdown Hill and elsewhere

Essex skipper (Thymelicus lineola) were recorded on the transect for the first time this year on 2nd July (Week 14) with six individuals successfully ID'd along with four small skipper (Thymelicus sylvestris) and a further six small/Essex. The transect also recorded two dark green fritillary (Argynnis aglaja).

Along with the butterflies - a great green bush cricket (Tettigonia viridissima) was also noted:

A quick walk on the hill on the 5th July, in less than suitable conditions (heavily overcast, with strong cool winds) - still managed to produce our first sighting of the year for chalk hill blue (Polyommatus coridon) a very wind blown male - persistently flighty - whilst I tried to grab a record shot. Essex skipper also provided a brief opportunity to get off some photos.

Also seen yellow shell moth (Camptogramma bilineata).

Returning to undertake the weekly transect on the 9th July (Week 15) two chalk hill blue males were recorded along with 13 other species of butterfly.

The Week 16 transect undertaken on 15th July - and saw the return on the wing of both small blue (Cupido minimus) - last recorded 20th June; and common blue (Polyommatus icarus) - last recorded 25th June. Strongly suggesting that a second brood had occurred with both species.

In total 20 butterfly species were recorded on the wing.

Following the transect a quick afternoon's visit to Hook Heath on the north of Portsdown Hill was rewarded with sightings of only one of the three target species - silver-washed fritillary (Argynnis paphia); failing to connect with white admiral (Limenitis camilla) and purple hairstreak (Favonius quercus).
