The utility model relates to an insect trap which comprises a barrel and two trapping plates. The trapping plates are arranged at the center of the top of the barrel in a criss-cross mode, and the trapping plate and the barrel are yellow. Due to the facts that the trapping plates connected together in the criss-cross mode are arranged at the top of the barrel and the trapping plate and the barrel are yellow, the insect trap can play a role of trapping insects flying close to the ground from different directions and enable specimen collection to be convenient, practical and efficient. Due to the fact that the tops of the trapping plates are provided with top covers, the insect trap can play a rainproof role. The insect trap is simple in manufacture, low in cost, convenient to carry, detachable and small in volume and can be conveniently carried to a field or a required place in use.
