Western paper wasp
Western paper wasp
The western paper wasp (Mischocyttarus flavitarsis) either live in forests close to rivers or on the underside of rooves near humans. Contrary to what you may believe, they actually don't like to sting as a first option. Instead, they would rather headbutt the threatening presence away. They are omnivores that feed on everything from other insects to nectar to animal corpses.

Ropalidia romandi is unique for its overall yellow color, with dark brown markings on its thorax and abdomen. Measuring around 1.2 cm, Ropalidia romandi is considered small. The first segment of the abdomen in Ropalidia is narrower than the following segments. Ropalidia romandi's front wings fold lengthwise when resting, which is a common characteristic of paper wasps.
European potter wasp
European potter wasp
The European potter wasp or European tube wasp (Ancistrocerus gazella) is a species of potter wasp. As an imago (adult), the female collects as many as 20 caterpillars for each nest, which consists of a single cell. Her larval offspring then feed on these inside the nest, which is sealed with mud arranged by her. As adults, they eat nectar and aphid honeydew. Males cannot sting, and the sting of a female is not painful. They can be found on windows, foraging for nectar on flowers, or searching out small cracks or holes in which to nest.

The Ancistrocerus campestris is primarily identified with the angry-looking smiley face on its back. When you aren't getting into a scowling match with their back, you may be admiring the unique nests that these types of insects make. The variety of nests puts them in a group of other wasps known "potter wasps." 
Bramble mason wasp
Bramble mason wasp
Bramble mason wasp differentiate themselves by their ability to mason cobblestone-like nests using pebbles. Unlike many other insects, their breeding sees the female solitary, constructing its offspring's dwelling in hollow structures. Additionally, these wasps play a critical role in environments, acting as efficient pollinators and aiding plant propagation. Furthermore, bramble mason wasp, as predators, help manage arachnid populations, providing an element of natural pest control.
