Yellow-legged hornet (Vespa velutina)

Yellow-legged hornet or Asian hornet (Vespa velutina) is an animal species in Vespidae, wasps with white or yellow tarsi, has about 13 subspecies, queens are 30 mm long and males 24 mm, workers 20 mm long and build nests to accommodate thousands of colonies.

V. velutina has a velvety brown or black chest with a brown belly. Each ventral segment has a narrow yellow border except for the fourth segment which is orange, black head and yellow face but varies widely in color and several subspecies have been identified by geographic coverage.

The female has a stinger to defend the nest and kill prey. Large egg-shaped nests up to 50 cm in length. The nesting season is long and the colony usually starts with building a nest in low bush, then leaves after a few months and quickly builds a new nest in the tree.

The oldest drawing specimen collection, Balaenoptera physalus Linnaeus, 1758 (OBS.296787995)

BLOG - Before the invention of photography, everything was explained by hand drawings that required naturalists to be able to draw to describe the specimens they documented. Scholars from taxonomy to medicine had to be able to sketch leaves to the human heart, this is why the academic world at that time had the subject of "art and science". A tradition that taxonomic drawings are accompanied by a measurement scale usually by placing a measuring tool in millimeters or centimeters or inches that supports scientific sketches has an identification context, but of course there are obstacles to having to document large specimens. I found a picture of a large specimen: Balaenoptera physalus (Linnaeus, 1758). Uniquely, the specimen with catalogue number: OBS.296787995 and stored at the Observation International, Aarlanderveen, Netherlands, is the oldest I have ever known. The shabby drawing with three folds and worn edges was made in 1547 or more than 500 years old. Previously I ...
