At about 6 inches (15 cm) long, this is one big, ugly grasshopper. Lubbers (Romalea microptera) are large, slow-moving insects that feed on vegetation. Their wings are vestigal, so they move by walking. This old male shows scars of mating battles with other lubbers, and you can see the pinkish wings where the protective covering has been broken. Lots of good information on the University of Florida web site here.
