The wing veins in the lower area are clearly visible and marked with dark scales. There are long fringes on the forewings. | | |

In the middle, an indistinct leaf shaped pattern (folium) is usually visible. Towards the back of the abdomen is a marking in the shape of an arrow or angle. Brown spots can sometimes be seen on the front of the abdomen. The sides are white to cream-coloured or light yellow, with the edges clearly separated. | | |

Due to their appearance, Helophilus trivittatus can easily be confused with Helophilus pendulus. However the females of the latter, have a clearly visible black stripe on the face. In addition, the white diagonal line on the 4th abdominal segment is broken in the middle in Helophilus pendulus. | | |

They immediately start searching for micro-organisms (yeasts, bacteria), which they eat with the help of their mouth parts, which are housed in a telescopic proboscis made from chitin. They breathe through two visible, protuberant tubes. Approximately 24 hours after hatching the larvae moult and thus reach the 2nd larval stage. After another 3 days, and 2 further larval stages, the development of the maggots ( now brownish in colour and about 3 mm in length ) is ... | | |

There is a dark brown diagonal stripe in the anterior third of the upper surface of the forewings, which extends up to the wing edge, and which remains visible when the wings are folded. Another transverse line in the same colour can be found in the posterior third of the wings’ upper surface. It runs from the wing joint to the wing tip. About halfway between these transverse lines, is a less distinct, wav... | | |

The wings of the males are grey-brown. The wing veins are brown and clearly visible. The wing bands are bright pale coloured and not so easily discernable. The females’ wings are reddish-brown. Their veins are a little lighter. | | |

In the centre of the folium, which is often darker on the males than on the females), white spots are visible, often in pairs. The legs of the Pachygnatha listeri are reddish or brownish in colour, long, shiny and without spikes or markings.
Pachygnatha listeri prefer wet and shady habitats, but can also cope with drier environments. . They can be found... | | |
