This is a pinned cicada mounted on a cork that swivels on a ball and socket. The device is called a posing stage. This setup is so I don’t have to handle the specimen as I am notoriously breaking legs and antennae. (See posing stage photo below)
This is a stereoscopic microscope or dissecting microscope. (1960’s) It is connected to the monitor which is showing a Bold Jumper spider.
This image shows a better view of the posing stage from Bioquip Products. This enables me to move the specimen all around by the handle without having to touch it.
