Helzer (1946-2008), Founder of Unicover Corporation. This painting appeared on the Fleetwood First Day Cover for the 33c Jumping Spider Classic Collection Series stamp issued October 1, 1999. Belonging to the Salticidae family, Jumping Spiders are distinguished from other spiders by four large eyes on the face and four smaller eyes on top of the head. More than 5,000 species of Jumping Spiders are known to exist around the world. Approximately 100 species of Jumping Spiders belong to the Habronattus genus, composed of primarily ground-dwelling, medium-sized salticids that are highly-ornamented. Most are ground-dwellers, preferring open ground with sparse vegetation, including dry leaf litter and sandy areas. Habronattus americanus are some of the most colorful species of Jumping Spiders. The males are known for their intriguing courtship displays that consist of elaborate dances. In addition, scientists believe the spiders' beautiful patterns and superb vision play an important role in their courtship behavior. The eyes of Jumping Spiders are among the best in invertebrate animals, providing them with unsurpassed depth and focus. Much like cats, they use their excellent vision to locate and stalk prey before pouncing. Incredibly, Jumping Spiders can jump more than 50 times the length of their bodies! Size: 14.25 x 12 in.
