Episyrphus balteatus, sometimes called the marmalade hoverfly, is a relatively small hoverfly (9–12 mm) of the Syrphidae family, widespread throughout all continents. Like most other hoverflies it mimics a much more dangerous insect, the solitary wasp, though it is a quite harmless species. The upper side of the abdomen is patterned with orange and black bands. Two further identification characters are the presence of secondary black bands on the 3rd and 4th dorsal plates and of faint greyish longitudinal stripes on the thorax.

E. balteatus can be found throughout the year in various habitats, including urban gardens, visiting flowers for pollen and nectar. They often form dense migratory swarms, which may cause panic among people for its resemblance to wasps. It is among the very few species of flies capable of crushing pollen grains and feeding on them. The larva is terrestrial and feeds on aphids. As in most other hoverflies, males can be easily identified by their holoptic eyes, i.e., left and right compound eyes touching at the top of the head (source: Wikipedia).

Hoverflies, sometimes called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects (source: Wikipedia).

Osmia rufa is a species of solitary bee, also known as the red mason bee due to its habit of using mud to build small cavities within its nest.

The species is most active during the spring and early summer although it can be seen as far as late June. Despite being classed as solitary, these bees are gregarious. The female is larger/broader than the male and has 2 large horns on the head.The female has a much smaller sting than honeybees or wasps.The male has no sting. The size is around 10 mm (source Wikipedia).

True flies are insects of the order Diptera (from the Greek di = two, and ptera = wings). They possess a pair of wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax.
Diptera is a large order, containing an estimated 240,000 species of mosquitoes, gnats, midges and others, although under half of these (about 120,000 species) have been described. It is one of the major insect orders both in terms of ecological and human (medical and economic) importance (source: Wikipedia)

Eristalis tenax is a European hoverfly, also known as the drone fly (or "dronefly"). It has been introduced into North America and is widely established.
The larva of E. tenax is a rat-tailed maggot. It lives in drainage ditches, pools around manure piles, sewage, and similar places containing water badly polluted with organic matter. The larva likely feeds on the abundant bacteria living in these places.
When fully grown, the larva creeps out into drier habitats and seeks a suitable place to pupate. In doing so it sometimes enters buildings, especially barns and basements on farms. The pupa is 10–12 mm long, grey-brown, oval, and retains the long tail; it looks like a tiny mouse.

The adult fly that emerges from the pupa is harmless. It looks somewhat like a drone honey bee, and likely gains some degree of protection from this resemblance to a stinging insect. The adults are called drone flies because of this resemblance. Like other hover flies, they are common visitors to flowers, especially in late summer and autumn, and can be significant pollinators.

In its natural habitat, E. tenax is more of a curiosity than a problem, and the adults are beneficial pollinators (source: Wikipedia).
Sarcophaga carnaria or the common flesh fly is a European species of flesh fly. Only males can be identified with certainty, and then only by examining genitalia. Lavae mostly feed on Earthworms. Adults are attracted to rotting meat and faeces.
The picture has been made with magnification factor 6 and f/13 using a Canon 7D, a Canon MP-E 65 mm f/2.8 and a Canon  2x teleconvertor. It is a single picture and has been made in our garden, while the fly was alive and kicking.

Sarcophaga is a genus of true flies, the type of the flesh-fly family (Sarcophagidae). This genus occurs essentially worldwide. These flies are generally well-sized and of a greyish color; like many of their relatives, the typical patterns are lengthwise darker stripes on the thorax and dark and light square dots on the abdomen. Many have conspicuous red compound eyes. These are set further apart in females than in males; the females are also larger on average. As typical for this family, it is almost impossible to tell the species apart from their outward appearance, and many can only be reliably identified by microscopic examination of the males' genitalia (source Wikipedia).

The adults are mostly predators on smaller insects — mostly other Diptera, they will also feed on pollen, but most specimens seen on flowers will be hunting prey there. Both males and females are found on dung, the males only feeding on other insects that visit dung, such as blow-flies. Females will be there both to feed and oviposit on the dung surface,
Females prefer to lay their eggs on the small hills of the dung surface and avoid depressions and pointed parts of the dung. This ensures survival, as emergence is better by avoiding the drying on small points in the dung. Also by avoiding possible drowning by rain by not laying eggs in depressions of the dung surface. The female yellow dung-fly is capable of making these decisions about her egg placement, and thus increasing possibility of success of her future generations. The eggs hatch into predatory larvae and feed on insect larvae within the dung. After 21 days or more of feeding, dependent on conditions, the larvae burrow into the soil around and beneath the dung and then develop into pupae, before developing into adult flies (source: Wikipedia).

The green shield bug (Palomena prasina) is a shield bug of the family Pentatomidae. It may also be referred to as a green stink bug, particularly outside of Britain, although the name green stink bug more appropriately belongs to the larger North American stink bug, Acrosternum hilare. The adult green shield bug ranges in the colour of their backs from bright green to bronze, without any substantial markings. Green shield bugs are a very common shield bug throughout Europe, including the British Isles, and are found in a large variety of habitats, including gardens. In Europe, the bright green shield bugs appear in May, having hibernated as imagos during the winter (Source: Wikipedia).
