Pachytodes cerambyciformis is a species of beetle belonging to the family Cerambycidae, subfamily Lepturinae (flower longhorns). [2]
Varieties include: [2]
Pachytodes cerambyciformis can reach a length of 7–12 mm. [3] These beetles have a quite compact body. Elytra are only about twice as long as broad, and clearly narrower towards the end. Head, pronotum and legs are black. Elitra are matt, light brownish-yellow, with black markings, which are very variable and sometimes absent. Usually they show two transversal black bands and a black apex. The first band usually is not continuous, while the second black band is narrower in the center. The suture is normally light brownish-yellow.
This species is very similar to Pachytodes erraticus . The differences are listed in the below table.
This beetle can be found in most of Europe and in western Asia. It is missing in the North Europe, while in Central Europe it is one of the most common species. In particular it is present in Albania, Austria, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Denmark, France, Germany, Hungary, Italy, Latvia, Lithuania, Luxembourg, Moldova, Netherlands, North Macedonia, Poland, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Switzerland, Turkey, Ukraine, United Kingdom. [2] [4] This species inhabit especially hilly and mountainous areas.
Adults are often encountered on flowers from May through August. [3] Larvae eat many species of deciduous and coniferous trees, [3] mainly feeding on the roots of Abies alba , Picea abies , Castanea sativa , Salix caprea and Aegopodium podagraria . [2] In April or May larvae leave the host plant and pupate in the ground. The life cycle is complete in two years.

Helophilus fasciatus, the narrow-headed marsh fly, is an abundant species of syrphid fly observed throughout the United States and Canada. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae of this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and farmyard manure or silage. The adults of this species lays eggs on vegetation overhanging the water. The larvae hatch and drop into the water.
Helophilus lapponicus, the Yellow-margined Marsh Fly, is a common species of syrphid fly observed across northern North America, northern Europe, Greenland and Siberia. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers, from which they get both energy-giving nectar and protein-rich pollen. Though common the larvae of this species are not known but the larvae of other species in this genus are associated with wet decaying organic material, particularly accumulations of decaying vegetation in ponds and mud and are a so called rat-tailed type.
Tragosoma depsarium is a species of longhorn beetle in the family Cerambycidae. It is the only one of its genus in Europe and is found mainly in cool regions of Northern Europe and Siberia, along with the high altitudes of the Alps and other mountain ranges. This beetle typically lives in open and manageable dry forest areas with old trees. Due to the decline of coniferous forests with a corresponding proportion of old wood, the beetle populations are also declining. In some regions of its range, including Germany, Tragosoma depsarium is considered endangered.
