The invention relates to an insect trap (10) and a method for attracting and/or capturing flying insects and/or insect pests (12). The trap (10) has a suction opening (14) which continues into a suction channel (16), in which there is an air flow (18) applying the suction opening (14) with a negative pressure or with a suction flow, and leading to an internal space (20) of the insect trap (10). The trap (10) also has a surface which surrounds the suction channel (16) near the suction opening (14), encases the suction channel (16) in a further region at a varying radial distance, widens in a direction parallel to the direction of the air flow (18) passing through the suction channel (16), and is at least partially permeable to out-flowing air (24), and which forms at least one part of an outer wall (22) of the insect trap (10). In addition, an end or base side (28) is provided, which is connected to the outer wall (22), is substantially impermeable to in- or out-flowing air, and is positioned opposite the suction opening (14), and which is at least slightly spaced apart from an open end side (30) of the suction channel (16) extending into the internal space (20) of the trap (10).
