A light-weight, transparent, elongated enclosure generally in the shape of a trapezoidal member, has an opening at a bottom end and at a top end, the transparent material being resiliently deformable. Two generally planar sheets of material are used, and are in overlying relationship, and are fastened together along opposed edges thereof. Squeezing together of the longest sides of the trapezoidal member by manual operation results in deformation of the two overlying sheets away from each other. This results in a continuous opening from a large side of the trapezoid at the bottom through to a top, short, side of the trapezoid at the top. In operation, the fly catcher is squeezed manually to provide an opening as described above, and is then positioned above the fly to be caught. The fly, sensing the pressure due to movement of the sending fly catcher flies upwardly and into the cone-shaped opening formed by the fly catcher. Pressure is then immediately released, and the sheets returned to their normal, generally planar state thus trapping the fly between the two sheets of transparent material. The fly can be exterminated by pressure if necessary. The remains of the fly are removed merely by repeating the manual squeezing operation on the sides of the fly catcher, permitting the remains to fall out of the enclosure. |
