A tri-wing or tri-plane.
Bi-plane
Biplane( bi-plane )
a biplane is an aeroplane with two sets of wings, one above the other.
An airplane with three sets of wings is called a triplane. Triplanes feature three wings stacked vertically, which can provide increased lift and structural strength compared to traditional biplanes or monoplanes. They were more common in the early 20th century, particularly during World War I, but are less prevalent in modern aviation due to advancements in aerodynamics and materials.

two sets of wings
Two sets fo wings (four total) and three sets of legs (six total). The prothorax carries legs, metathorax legs and wings, and meosthorax legs and wings. Not all adult insects have two sets of wings, but they all have six legs. Other arthropods have different parts all toghether.
ladybugs have two sets of wings
An airplane with two sets of wings is called a "biplane." Biplanes were commonly used in the early days of aviation and feature one wing stacked above the other, which can provide increased lift and maneuverability. They are less common in modern aviation, which typically favors monoplanes with a single wing structure.
An airplane with two sets of wings is called a "biplane." Biplanes were commonly used in the early 20th century for military and civilian aviation due to their increased structural strength and maneuverability. The design features one wing stacked above the other, which provides additional lift and stability compared to monoplanes.
