The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
When temperatures become too hot, wasps can be found in shaded areas or near damp places. ... Warm weather also means wasps could survive longer than normal, she said.
Approximately 300 species of Polistes paper wasps have been identified worldwide. The most common paper wasp in Europe is Polistes dominula. [2] The Old World tribe Ropalidiini contains another 300 species, and the Neotropical tribes Epiponini and Mischocyttarini each contain over 250 more, so the total number of true paper wasps worldwide is about 1100 species, almost half of which can be ...
The optimal temperature of the nest is around 32 °C (90 °F). However, when the temperature rises above the optimal temperature (during hot days), the workers use their wings as fans to cool the nest down. [15] V. vulgaris wasps recognise their nests by making pheromone trails from the entrance of their nest to the site of foraging. Those ...
Hornets (insects in the genus Vespa) are the largest of the eusocial wasps, and are similar in appearance to yellowjackets, their close relatives. Some species can reach up to 5.5 cm (2.2 in) in length. They are distinguished from other vespine wasps by the relatively large top margin of the head. Worldwide, 22 species of Vespa are recognized.

[67] [68] [69] Wasp nests made in or near houses, such as in roof spaces, can present a danger as the wasps may sting if people come close to them. [70] Stings are usually painful rather than dangerous, but in rare cases, people may suffer life-threatening anaphylactic shock. [71]
The German wasp is about 13 mm (0.5 in) long, has a mass of 74.1 ± 9.6 mg, [2] and has typical wasp colours of black and yellow. It is very similar to the common wasp (V. vulgaris), but unlike the common wasp, has three tiny black dots on the clypeus. To further complicate the issue this only applies to workers.
