Osmia leaiana – Allotment

Osmia leaiana

Distribution
Restricted to England and Wales. It is less frequently found than O. caerulescens, but occurs in similar habitats. Overseas: Europe, although at higher altitudes in southern areas; also north-west Africa, also at higher altitudes.
Habitat
The species may be encountered almost anywhere in England and Wales, but it requires cavities in dead wood, walls or cliffs for nesting.
Flight period
This species may be found between May and August.
Nesting biology
Nests in a variety of cavities, in walls, cliffs and dead wood. The nest closure and partitions are made from chewed plant material, bright green when fresh, which dries to a dark-brown, granular appearance.
Flowers visited
Recorded visiting a wide variety of flowers from a number of different plant families for nectar, but oligolectic on Asteraceae for pollen.
Parasites
The cleptoparasitic bee, Stelis phaeoptera, has been recorded as utilising this bee as a host (Westrich, 1989). It is likely that it is also attacked by the cuckoo-wasp Chrysura radians (Morgan, 1984)…BWARS

Andrena tibialis (Allotment)

Another new bee for me slightly worn Andrena tibialis

A. tibialis is widespread but very localised in England north to Yorkshire. It is univoltine and typically flies from mid March to late May. A range of habitats can be used, including heathland, quarries, sandpits and other brownfield sites, chalk grassland and occasionally gardens. It forages from a variety of flowers and spring-blossoming shrubs….. Steven Falk

Garden Snails – Helix aspersa

SONY DSC

Shell width is about 30mm. The Shell is light yellow-brown in colour, usually with extensive darker banding and blotching. Shell pattern, colour and size can be very variable. The umbilicus is completely sealed. The surface of the shell has a wrinkled texture. The flesh can be grey, grey-green, brown, or almost black. This snail is by far the most familiar to people – it is the archetypal garden snail. They eat a wide variety of fruit, vegetables and leaves. Lifespan is up to 5 years. When threatened, the snail creates many bubbles from its mantle to confuse predators. They can adapt to a wide range of conditions and are found in gardens, parks, fields, woodlands, dunes and vineyards. Helix aspersa are distributed across Europe and the Mediterranean and have been introduced to North America, South America, South Africa, Australia and New Zealand – they are the most widespread snail species.
