An insect trap for attracting and capturing flying insects. The apparatus includes a chamber for holding an insect attractant and exposing the same to a current of air, and having a first opening allowing passage of air but not insects therein. Positioned opposite the first opening, at least one funnel-shaped entrance to the chamber allows entry of the insects into the trap, as well as passage of air currents and entrained attractant odors out of the trap. An insect collection container, optionally having a one-way entrance, is also provided, and communicates with the chamber through a second chamber opening and the one-way entrance. Proper orientation of the trap in the wind is achieved by mounting a wind vane or fins onto the exterior of the chamber so as to position the first opening upwind, and the funnel-shaped entrance to the chamber downwind from the first opening. In the alternative, the wind vane may be omitted and the chamber constructed in the shape of a wedge, tapering toward the first opening, to enable trap orientation in like manner.
