Darren Woods 21/06/17

Hopefully this is the last day with temperatures above 30c, a sharp drop back to 20c will bring back out most of the insect families. Today in the dappled sunlight of the woods 14 species of hoverfly were seen with Leucozona laternaria being the best, also potted a Platycheirus that keys out to occultus [which would be new for valley], but I'll have to wait until the end of year for confirmation, when I send the specimens I've gathered to HRS. Due to the lack of flies other families and species become more prevalent and I spotted an unusual harvestman in Dicranopalpus ramosos which is new for me and probably the valley too. Meadow Browns are starting to emerge with half a dozen seen today.

 Dicranopalpus ramosos - identified by the combination of forked pedipalpus and resting posture with legs stretched to the sides.
 Leucozona laternaria
Chrysogaster solstitialis - should become very common over the coming weeks

30c meant it was too hot for hoverflies with only 10 species seen, all common. Managed to photograph Large Skipper at last, other butterflies were Speckled Wood, Common Blue, Red Admiral, Small Heath and  a single Ringlet. More Odonata were out today in Large Red Damselfly, Azure Damselfly, Emperor Dragonfly and Broad-bodied Chaser. Only moth of note was a Blood-vein, while the bees were all the usual suspects. Another Pachytodes cerambicyformis Longhorn beetle rounded off a quiet time. Photographed another Orchid, which looks different to the other one in an earlier post.

Orchid species - ??? - I've put it on Ispot

ISPOT - ID'd as Dactylorhiza majalis (traunsteineriodes) sub species Francis-Drucei. English name Western Marsh Orchid. That'll be new for me.

24c is about the limit for hoverflies, so went down the woods along the river in the shade and recorded 24 species with the highlights being Dasysyrphus pinastri [1st of year], Platycheirus ambiguus and Xylota sylvarum. Otherwise Stictoleptura maculata longhorn beetle was new for the year and Gwynne's-mining Bee was plentiful. The first unwelcome Notch-horned Cleg's were in full blood sucking mode and Speckled Wood and Large White were the only butterflies. New blooms included Stinking Tutsan, Water Figwort and Lesser Stitchwort.

 Gwynne's-mining Bee
 Eristalis tenax - watched this fly walk from the stones into the river about 10" dip its abdomen in the water for 5 seconds, then make its way back to land and onto the stones. I can only think that it was laying eggs knowing that the water would drop and the larva would live in the mud. There is no reference to this behaviour in any literature I could find. Or it could be just having a dip 😓.
 Dasysyrphus pinastri - very similar to "venustus" but in pinastri the yellow hooked spots on the abdomen do not reach the side margin of the tergites/abdomen.
 Chrysogaster solstitialis
Rutpela maculata

A fine not to warm day at 20c. Hoverflies were out in  force to coincide with the first bramble blooms here. I recorded a very healthy 36 species a few which are being assessed by HRS, so I'll update if anything new is confirmed. Firsts of the year included Scaeva pyrastri. Pipiza austriaca and Eristalis intricaria. Other highlights were Chrysotoxum cautum, Anasimyia contracta, all 7 species of Eristalis possible, Sericomyia lappona.

Other insects included 4 species of butterfly with Large Skipper first for the year, 6 species of Bumblebee, Broad Centurion soldierfly, Longhorn beetle Pachytodes cerambicyformis. The first emergence of Burnet moths. Had 100+ 5-spot Burnet in the central fields and also in the area that I had Narrow-bordered 5-spot Burnet larva there were 4 present which I assume were that species, but you really can't tell the adults apart. Unusually I had Middle-barred Minor feeding on Umbellifers during the day.

Counted 3 pairs of Stonechat and 9 Whitethroats calling on my walk. Also had 20 new blooms for the year, so the rain did have some positive effect.

First day of fine weather for what seems like an eternity. Insects were out in force with 25 species of hoverfly. A large emergence of Syrphus species was noted with over a 100 of torvus and ribesii. New for the year were Baccha elongata and Didea fasciata. With other good sightings including Melanostoma mellinum, Xanthogramma pedissequum, Sericomyia lappona, Criorhina berberina and Xylota jakutorum. 5 species of butterfly, 7 species of Bumblebee were seen. Willow Tortrix added to the day moths and a Broad-bodied Chaser dragonfly was new for the year. Finally Pachytodes cerambicyformis [longhorn beetle] was on bramble.

Also some first of the year blooms in Bittersweet, Tutsan, Cross-leaved Heath, Cut-leaved Dead-nettle and another type of Orchid.

According to locals sheep are too stupid to lead the flocks between pastures, so they use a single goat to lead the flock instead, flocks are usually 300+ strong and they follow the goat everywhere. They can't use Rams as they only have one thing on their minds when they see 300 sheep 😈.

Georgia butterflies

I recorded 16 species of butterfly in Georgia, while others on the trip saw about 10 more. Many of the species are the same we get in this country with a few exceptions in Black-veined White, Turquoise Blue, Spotted Fritillary, Queen of Spain Fritillary and Scarce Swallowtail.

The heavy rain over the last week has taken its toll on the Hemlock Water Droplet patch in the woods, with 50% of the plants damaged or destroyed. Nevertheless I had 22 species of hoverfly with Dasysyrphus albostriatus and Riponnensia splendens being my first of the year. Only other insect of note was a longhorn beetle Rhagium mordax although my shot is a little out of focus. Good numbers of P. conwagana [ Tortrix moth] out today.
