Dragons and Damsels Emerge

This week has seen the emergence of several species of Odonata (dragonflies and damselflies) on Pevensey Levels. My first Hairy Dragonfly (Brachytron pratense) of the year was a newly emerged female in the process of expanding her wings. Although the Large Red Damselfly (Pyrrhosoma nymphula) has been on the wing for two weeks on the levels, Azure Damselfly (Coenagrion puella), Variable Damselfly (Coenagrion pulchellum) and Blue-tailed Damselfly (Ischnura elegans) have all started to emerge this week.

Earlier this week, I met up with Bob for our regular Wednesday walkabout. We headed for the downs in search of orchids. I also saw my first Small Copper (Lycaena phleaes) of the year which just happened to be an aberration, sporting yellow pigment in the middle of the forewings. The specimen was also of form caeruleopunctata which gave this phleaes a rather attractive livery.

The light trap in my wealden garden this week has started to attract species of one of my favourite moth groups, the Prominents (Notodontidae).They are so named because of the body and wing tufts that show when the moths are at rest. The first three species are Prominents and the last species is from the Noctuidae family.

A Holly Blue Encounter and the Twelve Forty-five to East Grinstead

On Easter Monday I decided to try and make use of the patchy early morning sunshine and headed off to Pevensey Levels. The weather forecast was right however and by the time I started my walk, the grey cloud had settled across the whole sky. I concentrated my efforts on searching for any roosting Holly Blues (Celastrina argiolus) that might be tucked away in any ivy growth. After an hour or so I found a freshly emerged female settled low down in a hedgerow. Looking up at the sky, there were a few small patches of blue sky appearing and so I sat nearby and waited. Another hour passed and then the sun managed to peep through the clouds for a brief few moments, enticing her to open her wings.

The next day we met up with friends at the Bluebell Railway at Sheffield Park where the Flying Scotsman had been visiting over the Easter holiday. Whilst I am not hugely knowledgeable on steam locomotives, the excitement and affection in the crowd was palpable as this magnificent piece of 1920's engineering set off for East Grinstead.

The Holly and The Ivy

The Holly Blue (Celastrina argiolus) spring brood will lay their eggs on the buds of holly but the summer brood will mainly use ivy as the host foodplant. All the Holly Blues on the wing at this time of year fed as larvae on ivy last summer and therefore the best place to look for argiolus activity is on and around favoured ivy growth where the males concentrate their search for freshly emerged females. This species has been performing in good numbers on Pevensey Levels.

Spring Emergence Moves On Apace

I keep having to remind myself that we are only just entering the second week of April. The hot weather during this last week has felt more like June or July and the emergence of our Spring butterflies has really moved on apace. Although I have yet to see a Large White (Pieris brassicae) on the wing, I have seen most of the other early Spring species in multiple numbers.
 
I saw my first Green-veined Whites (Pieris napi) on Pevensey Levels (2nd April) and my first Speckled Woods (Pararge aegeria) near Arlington (5th April).
 
The weather was again hot and sunny on Pevensey Levels yesterday. Holly Blues (Celastrina argiolus) were numerous, with three or four males at a time seen patrolling the hedgerows in search of females. I also saw my first Large Red Damselflies (Pyrrhosoma nymphula) of the year (9th April).
