The image is a medieval illustration, likely from a manuscript, depicting a large flea. The flea is rendered in dark ink with a detailed, somewhat grotesque, depiction of its anatomy. It has six legs and a bulbous body. The background is a warm, golden-brown color. At the left and right sides of the image are stylized plants with green leaves and red stems. Below the flea and plants is a line representing the ground, rendered as short, dark strokes. The entire image is framed by a decorative border with repeating geometric patterns in red and gold.
