| ...proboscis, which is mainly used to sting and inject enzymes into prey is not held next to the body in resting position. The proboscis can produce sound when it is moved through a longitudinal groove in the anterior of the underside of the chest. The scutellum has a yellow keel and a blunt spine at the end. | | |

| ...urnal flies reach body lengths of 2-20 mm, with the length varying according to what species they are. They are primarily black in colour with grey tires. They are often very hairy, especially their abdomens. Tachina flies can be identified by their scutellum. This bulges at the rear edge of the upper side of the chest - just like a bead segment. Their sensors are tripartite. At the front of their heads there are sucking (sometimes piercing and sucking) mouth parts. | | |

|
| Adult Eupeodes corollae reach body lengths of 7 - 11 mm. Their antennae are yellow-brown to dark brown in colour. The scutellum is hairy and light yellow in colour. The legs and hips are black and yellow. The abdomen is oval and has 3 yellow stripes, which run to the lateral edges. In the females these stripes are discontinuous not linked, while in the males they are usually... | | |

| There is a single defensive gland on the underside of the posterior segment of the chest (metathorax) which can release a very unpleasant-smelling secretion. There are 3 to 5-yellowish-white granules at the front edges of the scutellum. The abdomen is almost completely covered by the transparent hind wings, and in some specimens there are several black spots on the sides of the abdomen, which run lengthwise. | | |
|
| Due to their physical characteristics, the southern green stink bug can be confused with the green shield bug (Palomena prasina). The latter is about 1 mm smaller and has no clear grainy boundary at the front edges of the scutellum. A key identifying characteristic for both species is the shape of the orifice of the defensive gland outlet. In the southern green stink bug it is short and wide, and in the green shield bug it is elongated and oval. | | |
|
| These small, slender hoverflies reach body lengths of 7 - 10 mm. The abdomen has 6 grey patches, which extend to the edges. The legs are black and yellow in colour. The knees are broad. The mesonotum and scutellum are black and shiny. Platycheirus albimanus are found in almost all habitats, although they prefer moist, shady places. | | |
|
| The upper surface of the chest is mostly whitish-grey, whitish-yellow or yellow in colour. There are 3 wide black stripes in the middle. The scutellum is yellowish-brown with a light olive sheen and has, a very thin, central, whitish-yellow stripe which runs lengthwise. | | |
|
| The bodies of these insects are black, shiny and oblong. There is a yellow, transverse stripe on the pronotum and the carapace is black without markings. The scutellum bears a yellow patch. The first abdominal segment is stalk-shaped, and the second to fifth segments have a yellow stripe which is non continuous on the fourth segment. The legs are yellow but have a dark base. | | |

| ... mm. Their upper body surface is brightly coloured (yellow and orange) and pitted. Between these indentations the surface is ‘wrinkled’. There are 4 longitudinal black stripes on the upper surface of the pronotum the inner two of which converge. The scutellum has 5 dark spots. These insects are unusually shield-like in shape.
The antennae are dark and have 5 segments, the first of which is brownish. The tapered side edges of the first chest segment are particularly striking. The wing covers (elytra) ... | | |
