Thankfully the weather has been kind to us for the duration of National Insect Week and RSPB Rainham Marshes has been alive with a plethora of insects. The first proper flush of Meadow Browns have emerged along with Ringlets, Small and Large Skippers. Speckled Woods are dancing once again and the first Marbled White of the season was gliding along the river wall on Friday.

Dragonflies have also emerged from their watery larval homes and Brown Hawkers and Emperors are now cruising the ditches with the odd late Hairy Hawker, Broad-bodied and Four Spot Chasers and Black-tailed Skimmers while Ruddy Darters are hunting from the brambles in the woodland but have as yet, not turned pillar box red.

Red-eyed and Common Emerald Damselflies have joined the trio of Blues and all eyes are open in the hope that one of us will find the first Green-eyed Hawker or Scarce Chaser for the reserve as both these species are increasing in the south-east.
I managed several hoverfly hunting sorties and found a good selection with at least 24 species identified confidently!
- Chrysotoxum bininctum and verralli,
- Xanthagramma pedissequum agg,
- Sphaerophoria scripta,
- Eupeodes luniger and corolla,
- Meliscaeva auricollis,
- Episyrphus balteatus,
- Syrphus ribesii,
- Cheilosia illustrata,
- Neoascia interrupta,
- Eristalis pertinax, tenax, nemorum, arbustorum and inticaria,
- Eristalinus sepulchralis,
- Helophilus pendulus and hybridus,
- Parhelophilus versicolor,
- Volucella bombylans and pellucens,
- Syritta pipiens,
- Tropidia scita.
There were lots of Blue and Greenbottles around and paddy footed Flesh Flies and hopefully Phil will narrow down one or two for me along with an impressive Tachinid with rather protruding mouth parts and i will then add some more images.
The biggest Soldierfly I have ever seen whirred past me and felt more beetle like in flight! It was a Flecked General - Stratiomys singularior which was then seen supping on the smelly Hogweed in the Cordite three days on the trot!

And all the time we were watching all these lovely insects we were having to keep an eye on the marauding Clegs who were homing in on us for blood... I also saw a couple of chunky Tabanus autumnalis and only my second in the field Hybomitra ciurea - the Levels Yellow Horned Horsefly. Most records are of ones on the inside of the visitors centre window!

The first Cockchafers were on the wing and it is always pleasing to find my favourite longhorn beetle with the best Scientific name I know. - Agapanthia villosoviridescens.

Glow-worms were seen crossing the paths most days whish was a good omen for Friday night and golden Sun Beetles scurried out of the way. I have a bit of history involving one of these quarter inch long lovelies, a red hibiscus patterned shirt, my inner ear and a glass of water but I may save that traumatic ‘while at work’ story for another day...
Bumblebees seem to be around in good numbers and it was pleasing to find Tree - Bombus hypnorum, Shrill - Bombus sylvarum and Brown Banded – Bombus humlis amongst the more usual species. Several large Andrena were seen but I am still working on the id.
Bryony Bees are still nectaring on the White Bryony around the trail but particularly near the centre and the progeny of the slightly furry Bryony Ladybirds can now be easily located on the undersides of the same leaves.

And so to our Late Night Opening yesterday where we were treated to a clear blue sky and speedy sunset complete with Barn and Short-eared Owls and a productive mothing session in the Wildlife Garden through to about 1130 where about 30 or so species came to the light while we all gathered round and watched.
These included such great names as the Phoenix, Scarce Footman, Heart and Dart, the Snout, Angle Shades and the Gothic but it was the duo of Elephants that stole the show with singles of Small and Large Pachyderms although the latter waited till we were packing up to appear unlike the enormous Privet Hawkmoth that clattered around the top of the willow tree on several occasions!
|Phoenix - apparently a scarce moth and a new one on me|
As usual we were kept company by several Common Pip bats and both Barn Owl and a Whimbrel were heard. There was one species we all wanted to finish up a superb evening and that was Glow-worm and a scout around the car-park and ramp verges resulted in ten illuminated females and two males – one of which was busy making more Glow-worms and the other that was attracted to my moth bulb and obviously thought his luck was in!

I finally got in at about 1am and managed a few hours kip before a relaxing day but I was determined to do something insecty and so headed down to Grove Ferry in the late afternoon sunshine to look for Green-eyed Hawkers. They have been established here for a few years now and are thought to be of continental origin rather than from Norfolk dispersal but I had never made the time to go and look for them.
As it happened they were a doddle with seven or eight seen over a short walk. There are an impressive dragonfly with burnt orange bodies, transparent wings and glowing green eyes. They were very active and I doubted one would alight near me despite hunting just yards away but eventually one did and I snapped a couple of pics before it resumed its search for prey.
Scarce Chasers and Black-tailed Skimmers dashed around the pools and a Green Sandpiper was suggesting that returning birds are already on their way while a Turtle Dove zipped through and brought a smile. My circuit added Banded Demoiselle to the dragon list and a Kingfisher and Cuckoo to the bird one before fish n chips in Herne Bay and a swift journey home.
Tomorrow sees me helping at a countryside fair so I am going to have to work hard to find my insect of the final day of this fantastic week long event...
