The larvae breathe through a "snorkel", which is attached to the tip of the abdomen and runs up to the surface of the water, hence the name rat-tailed maggots. The larvae can reach lengths of 20 mm and feed on putrid sludge and dead organic matter, which they filter from the water. They make an important contribution to water clarification. | | |
| | The larvae are equipped with a kind of snorkel (hence the name rat-tailed maggot), up to 100 mm in length which has its base on the abdomen of the larvae and reaches up to the water's surface. The larvae pupate after 2 weeks. | | |
| | | Adult Nezara viridula reach body lengths of 12 - 16 mm. Their bodies are egg or shield shaped and dull green in colour. The upper surface of their bodies has individual or converging little pits, often with a whitish rim. The head and antennae are dull green. The antennae are divided into 5 segments. The eyes can be red or black in colour. | | |
| | ... bugs extends from spring through to late autumn. The fertilized females lay their eggs on the leaves of different plants such as Crotalaria, wild blackberry (Rubus) and Cyperus rotundus. They glue about 260 barrel-shaped, whitish-yellow eggs to the surface of the leaves, in groups of 30 - 130. The eggs are about 1. 1 mm in length and 0. 9 mm in width and turn pink over time. | | |
| | ...legs are transparent, while the rest of the body is yellowish. From the beginning of the 2nd larval stage on (5 days) the nymphs start eating. The head, thorax, antennae and legs are now black. There is a yellow patch on each outer side of the upper surface of the chest. The abdomen is red, as are the 2nd, 3rd and 4th segments of the antennae. In the 3rd and 4th larval stages (7 days), the body shape changes and shades of green start to predominate in the colouration. In the 5th stage (8 days) the wing... | | |
| | 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 lengthwi... | | |
| | ... oxygen content of the water plays a decisive role, as egg-laying can even take place in cesspools. From these eggs the so-called "rat-tailed maggots" hatch – larvae with a long breathing tube attached to the abdomen that extends up to the surface of the water. The larvae feed on decaying organic matter and thus make an important contribution to water clarification. | | |
| | Adult Anthrenus pimpinellae reach body lengths of 2 - 4. 5 mm. Their bodies are relatively small and oval in shape. The upper surface is covered with scales and has a black base colour. The antennae have eleven segments, the last three of which form a club. The pronotum (neck plate) is covered with reddish-yellow and white scales, with darker patches in the middle and at the sides... | | |
