Insect trap and method for attracting and/or capturing flying insects

A device to act as an insect trap (10) comprising:

• an outer wall (22), including an at least partially air-permeable portion that is permeable to a first air flow (24), and a front side (28), with a collar (32), that is largely impermeable to air flow, wherein the outer wall (22) adjoins the front side (28) at the collar (32);
• and
• a suction duct (16) with an intake (14), an outlet (30), and a fan located inside the suction duct for generating a second air flow (18) from the intake (14) to the outlet (30),
• wherein the outer wall (22) attaches to, and surrounds, the suction duct (16) in a vicinity of the intake (14),
• wherein a radial distance from the suction duct (16) to the outer wall (22) increases as the outer wall (22) approaches the front side (28) in a direction of the second air flow (18),
• wherein the suction duct (16) extends from the intake (14) to the outlet (30) into an interior space (20) enclosed by the outer wall (22) and the front side (28), and the outlet (30) is radially spaced apart from an inner surface of the outer wall (22), and
• wherein the front side (28) and the collar (32) upwardly deflects the second air flow (18) to create the first air flow (24) through the at least partially air-permeable portion of the outer wall.
