This is the largest Colletes hederae aggregation I have found , the whole ploughed trough along the path was filled with bees and their burrows.
I have posted information on these relatively new bee to the UK before which you will find in the link below
Devil’s coach horse
The Devil’s coach horse is a long, black beetle with short elytra (wing cases). At first glance you could mistake it for an earwig.
A nocturnal predator, this beetle lives in and around decaying matter. During the day it tends to rest among leaf litter or under stones. Females lay their eggs in the soil, and these hatch into carnivorous larvae…. RSPB
I watched this hornet being taken out by a guard hornet at the nest , I have no idea why whether it was an intruder I don’t know. Both fell to the floor one flew of and this one I put on a log out the damp grass thinking it had been stung and was dying but actually after about 10 minutes it started to come back around and eventually flew off.
It is up to 25 mm long and 4 mm wide, and has about 20 segments. This is a flattened, brownish millipede with off-white legs.
There are several very similar species which can only be confidently identified using a key and a microscope or good lens.
Gardens and woodland, often found in dead wood, compost heaps and leaf litter.
When to see it
All year round.
Normally feeding on dead leaves and other rotting material, but also fond of soft fruit such as Strawberries.
Widespread and common in Britain… naturespot
Locally common all over the British Isles. It occurs in almost all of Europe and Palaearctic Asia.
Status (in Britain only)
Common. The species is not regarded as scarce or threatened.
Prefers sunny, warm, damp habitats such as meadows and river banks but found in most open urban and agricultural areas, woodland edges, parks and gardens. Rarely found in hot, dry, sparsely vegatated areas.
Nuptial flights usually occur during August and September.
They feed on honeydew from aphids and scale insects and drink nectar from flowers. They are aggressive and sting freely.
Nests are in the ground, in tufts of grass, under stones and in rotten wood. Colonies are usually polygynous with an average of 15 queens and a thousand workers or more…. BWARS
