A light trapping device for teaching aid includes a sunshade, a trapping assembling, and a light source platform. By operating variables, such as wavelength of the illumination member, amount and width and intervals of the light holes, distance of the light source, and attraction time duration, different functions including scientific research and teaching aiding and practical utilities are achieved.

The invention projects light by the illuminating member of the light source stage toward the capturing component, and utilizes the phototaxis characteristic of the insect to attract the insects in the receiving surface of the opaque space. The insect is attracted by the light, and are captured by sticky pieces. The invention has both scientific inquiry and teaching and practical functions.

The present invention relates to an insect trapping device, and more particularly to a device for attracting insects by utilizing the habit of phototaxis of insects. The invention has both scientific inquiry and teaching and practical functions.
