The proboscis (rostrum) starts below the back of the head (in the hip region of the first pair of legs) and hangs backwards on the underside of the chest (thorax). | | |
| | ...ents can also be yellow-brown, reddish-brown or pure yellow in colour and the stripes can be brown instead of black, or completely missing. The first abdominal segment (propodeum) usually has dense and dotting hair on its surface. The females have a sting for defense at the rear which is missing in the males. The females have strong bristles on their front feet which they use todig. The bee wolf can easily be confused with Bembix rostrata. | | |
| | | Female velvet ants reach body lengths of 3-20 mm, have no wings, are very hairy and have a defensive sting, which can cause a lot of pain. An important characteristic, distinguishing these wasps from other wingless wasps, are the fine bristles as also as elongated pits, which they have on their sides and are known as "felt lines". | | |
| The mouth parts of phantom midges are atrophied and functional in some species and in others not. Phantom midges cannot sting. Their eyes do not touch but create a crescent shape around the base of their antennae. The long antennae of the males are feathered and comprise 13-15 segments. The pedipalps are divided into three to five segments. Dot eyes (ocelli) are not e...
...Their eyes do not touch but create a crescent shape around the base of their antennae. The long antennae of the males are feathered and comprise 13-15 segments. The pedipalps are divided into three to five segments. Dot eyes (ocelli) are not existing on them. The thorax (chest) has no continuous, V-shaped suture, as in the case of mosquitoes (Tipulidae). The wings of the females are black in colour and almost reach the end of their abdomen. The legs of the Chaoboridae are formed like stilts.... | | |
| | ... amongst the female workers of the new hornet colony which resembles the pecking order amongst chickens and this can create aggression, which leads to more or less heavy fighting between individual female workers. When this happens workers may sting each other resulting in deaths. If the population of the nest expands greatly and there is no room for further development all the hornets move to a more suitable place and establish a new nest (branch formation). | | |
| | ... although their appearance and colouration can vary widely. There are many species which are bright green, red or yellow in colour and with various patterns which create a partial resemblance to Vespidae (wasps), but Tenthredinidae are not able to sting. The so-called "wasp waist" is absent. Their antennae can have 7 - 15 segments, but mostly have 9 segments. | | |
| | The legs of Philodromus aureolus are brown to yellow in colour, can be spread out horizontally and allow the spider to move at speed. The tibia of the first leg pair to the bottom is with two pairs of long, and just outside one pair of short sting-like bristles. In particular, the males are very fast runners. | | |
| | Coranus aegyptius have a short, strong proboscis (rostrum) which is strongly curved downward and is divided into three parts. The 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. | | |
| | This is achieved by small, dark, often tiny midges with body lengths of 0. 6 - 5 mm. Most species average around1. 5 mm in length. Scatopsidae are hairless They cannot sting. Due to their appearance they can be confused with black flies (Simuliidae) but they normally do not have an arched chest (thorax). | | |
| | The life span of Bibio clavipes is very short. This species is one of the few bibionids, which are active in September. Bibio clavipes feed on nectar and honeydew and do not sting.
Bibio clavipes reproduce once a year. During mating season, partners come together in large swarms. Fertilization of the females starts in the air and is completed on the ground. | | |
