Post hurricane post

The weather continues to be hateful, but I'm guessing that everyone has been in much the same position.

I went up to the boggy area which has many specimens of the late nectar source, Devilsbit Scabious, and found this specimen of the hoverfly Sericomyia silentis. For those of you who know the size of the flowerhead, it will be apparent just how large this hoverfly is.

Devilsbit is a plant that loves damp, acidic soil, in complete contrast with its close relative, Field Scabious, which needs alkaline soil. Interestingly enough, I sometimes find an occasional specimen of Devilsbit Scabious which has the same colouring as the lime lover:

It's still 100% Devilsbit, though.

Staying with Devilsbit, I found a few rather interesting specimens that were making an extra flowerhead from an existing one:

Notice the second 'offshot' appearing to the lower left of the central flower. This phenomenon wasn't restricted to one area of the bog: I found multiple specimens spread over perhaps 200 m.

Some specimens of Angelica have survived the storms: these are mostly ones in very sheltered locations. Specimens out in the open have all snapped at ground level. This flowerhead had a number of Ichneumonids still nectaring on it. There are 3 in this shot:


Actually, I just spotted a fourth, right at the bottom of the shot.

This area has quite a few Scots Pines, and I found a few specimens of Suillus flavidus and its bigger brother Slippery Jack, which are always found in association with Pine. I also found the usual swarm of Hebeloma mesophaeum all the way along the edge of the access road:

The mosses are Pleurozium schreberi (red veins) and Rhytidiadelphus squarrosus (green 'stars' at 4, 6 and 8 o'clock).

I recently showed a specimen of the leafhopper Cixius nervosus, but I thought this one showed off those wonderful wing veins at their best.

Leaf hoppers - like so many other true bugs - are quite difficult to separate, but the main identification features are visible in this shot.

1) There are 3 'keels' on the thorax.
2) The black dots on the wing edges are larger than those on the inside veins of the wing
3) There is a rather distinct black bar across the front third of the wings.
4) The area between the eyes and the thorax is brownish-yellow.

Let's hope next week's fungal foray isn't rained off.

Angelica time

The Angelica flowered this week, so for the next 3 weeks I will concentrate on nectaring insects. Angelica is a major source of nectar for bees, flies, hoverflies, wasps, sawflies, ichneumonids, beetles and various bugs, so it's always worth a close look.

Here's a shot of the impressive flowerheads just before they burst open:

As I was walking between Angelica plants, I saw a dead bumblebee lying on the path, but it suddenly moved.  I looked closer, and saw that one of the Formica ants was pulling it laboriously over the path, presumably towards its nest:

Progress was rather slow, since the bee's claws kept getting stuck on stones, and the ant had to keep going back to free them. This slow progress went on for a while, and then the ant seemed to pause for a moment, then it went under the bee and somehow managed to flip it over onto its back. The ant went back to pulling the bee and progress was much faster, since the bee was sliding along on its glossy wings and the claws were safely in the air:

The whole procedure was watched by the much smaller red ant to the left of the first image.

It's clear that ants have great strength, but it also appears that they have reasoning power, too.

Cixius nervosus is one of the leafhoppers, and can be distinguished by the triple 'keels' on the thorax, and the lacy veins on the wings:

Crane Flies are the 'Daddy Longlegs' that are so numerous at this time of year:

Their larvae are the 'leatherjackets' that eat the roots of grasses, often ruining large areas of lawn.

I rather like the way the leaves of the Cleavers mimic the legs of the Cranefly on that shot.
