Nigma puella
Nigma puella is a species of spider belonging to the family Dictynidae. It is found in Europe, Azores, Madeira, Canary Islands and parts of North Africa. Like most members of the family, this is a small spider but the female is striking, with a light green abdomen marked with a bold maroon blotch and a variable amount of barring in the same colour. The male is reddish brown. This species makes a horizontal web over the top surface of a leaf. References
