The present invention relates to an insect trapping device comprising a first body, a first joint portion is disposed on a periphery of the first body, and a second body is movably fixed to the first body, the second body is The peripheral bending ring is provided with a second joint portion corresponding to the first joint portion, and the second joint portion can generate an elastic force for outward stretching, thereby being elastically tightly coupled with the first joint portion. The fixing is fixed, so that the first body and the second body cannot be easily disassembled and separated. Further, the first body and the second body can be quickly assembled and stacked for convenient carrying and transportation.本創作係關於一種昆蟲誘捕裝置，包含有一第一本體，該第一本體之周緣係設有一第一結合部；一第二本體，其係與該第一本體活動結合固定，該第二本體之周緣係彎曲環設有與該第一結合部相對應之一第二結合部，利用該第二結合部可產生向外撐張的一彈性力，藉以可供與第一結合部相互彈性緊密卡合固定，使該第一本體與第二本體無法輕易拆解分離。進一步可供迅速組裝及疊置多個第一本體及第二本體，以方便攜帶及運送。
