Phototaxis is a kind of taxis, or locomotory movement, that occurs when a whole organism moves towards or away from stimulus of light. This is advantageous for phototrophic organisms as they can orient themselves most efficiently to receive light for photosynthesis. Phototaxis is called positive if the movement is in the direction of increasing light intensity and negative if the direction is opposite.

The arthropod trap has a base with a plurality of sides that angle upwardly and inwardly toward a capture area in the center of the base. Multiple outwardly-projecting fins are disposed on or adjacent to the sides of the base. The fins also angle upwardly toward the capture area so that the fins guide arthropods into the capture area. The capture area includes a pitfall so that the arthropods topple through a pitfall opening and are retained in the pitfall. A trap cover fits over and at least partially conceals the capture area. In one embodiment, the trap cover provides a platform for the placement of light emitting diodes that emit light in a wavelength that appeals to the positive phototaxis instincts of the target arthropods.
