| Miridae have antennae with 4 segments and have simple eyes (ocelli). The front wings are only slightly hardened (hemielytra). | | |
|
| The membrane of the wing is dark brown with black brown veins. In addition to the triangular section of the front wing tip (cuneus), there is a brighter spot. Due to their appearance, Plagiognathus arbustorum may be confused with other species of the genus Plagiognathus. | | |

| ...s. Their antennae are long and thin. Their mouthparts consist of an intermediate form of tools to chew and suck. Some species also have spinning glands. The males’ forewings at their rear edge are reversed like a hook and thus hand along the thicker front edge of the rear wing, while the females have stunted forewings or no forewings at all. | | |
|
| ...and is partially covered by the wings. The penultimate (6th) segment of the abdomen has a black upper surface with five, bright irregular spots. The edges of the abdomen have a yellowish-brown and black pattern. The wingspan is about 14 mm. The front section of the wing is leathery and has a fine, dense stippling, while the rear section has a glass-like shine with numerous veins. The legs are brown to yellowish-brown in colour with brown spots. | | |

| ...of gills are located laterally, the first six pairs of which work almost continuously. At the end of its abdomen it has 2 long and hairy (whitish and filamentary structured) tail appendages (Cerci), which are much longer than the entire body. The front wings are crystal clear (like glass) and have very noticeable dark veins. The rear wings are missing. | | |
|
| Their antennae have 16 segments or more and do not bend. The venation of the wings is very diverse. An important criterion for identification is the absence of a particular vein on the front wings. The trochantersof the hind legs comprise 2 segments. Female braconids have very long ovipositors, which can differ in length even within a species. The great length of the ovipositor, up to fourteen times the actual body length, is required f... | | |
|
| Adult Gasteruption species reach body lengths of 5 – 15 mm. They are characterized by their seemingly elongated neck and abdomen; the latter issignificantly thicker towards the rear and easily recognizable. The front wings are folded lengthwise. | | |

| ...ight red compound eyes. The 3rd antennal segment is short and ovoid. The antennae are inclined downwards from the 2nd segment on. A small triangle of ocelli (simple eyes) can be seen on the upper half of the forehead. Orbital bristles reach from the front edge of the eyes to the edge of the forehead. The upper surface of the chest (thorax) is brownish-black in colour and also has bristles. The scutellum is rusty brown. The wings are transparent with a reddish-yellow sheen and have 2 diagonal veins wh... | | |
