This is a real Javan Vinegaroon (Thelyphonida) shadowbox diorama!
Native to Indonesia, these are also known as whip scorpions. Though they visually resemble scorpions, they are actually in the spider family (arachnids)!
They earned the name Vinegaroon from the fact that they can defensively excrete an acidic chemical with a vinegar-like odour.
This real insect comes framed in a ~6.25" tall riker box and would make a great addition to any collection.
