An insect trap includes a base seat and a cover lid. The base seat includes a bottom end that circumferentially defines a plurality of guide holes and forms an induced space. A top part of the base seat is circumferentially configured with a containing tank, in which a decoy is placed in the containing tank. The base seat and the cover lid form a collection space. Accordingly, insects can be seduced to enter the collection space via the induced space on account of the smell of the decoy placed in the containing tank of the base seat, to thereby form an environmental insect trap.一種昆蟲捕捉器,包括:一基座及一罩蓋所組構,該基座底端環圍設置複數導引孔且形成一導入空間,又基座頂部環圍設有一容置槽,而基座與罩蓋結合形成一收集空間,其中該容置槽間設置誘餌,藉此,經由容置槽的誘餌所散發之氣味,可導引昆蟲由導入空間進入收集空間內,形成一具環保之昆蟲捕捉器。1...昆蟲捕捉器10...基座100...導引孔101...導口102...容置槽11...罩蓋110...收集空間111...氣孔
