An insect capturing device includes a casing, a capturing roller, an opening, a driving device and a blocking plate. The casing has a receiving space divided into upper and lower portions. The capturing roller coupled to the driving device is disposed in the upper portion and one side thereof is exposed by the opening. In this case, an insect on the capturing roller at the opening is transferred all the way into the lower portion of the receiving space while the capturing roller is rotated by the driving device. The blocking plate is arranged close to the capturing roller and is located in the receiving space, such that the insect transferred into the lower portion is blocked by the blocking plate and falls in to the lower portion to be trapped.一種昆蟲捕捉裝置,其包括殼體、誘捕滾輪、開口、驅動裝置及擋板。殼體具有劃分為上部及下部之容置空間,誘捕滾輪設置於上部內,開口位於上部使誘捕滾輪之一側露出,使昆蟲透過開口而附著於誘捕滾輪上,驅動裝置連接誘捕滾輪,使其轉動同時將昆蟲向下部帶動,擋板位於容置空間內,且至少一部分與誘捕滾輪緊密設置。其中,在誘捕滾輪轉動時使昆蟲接觸擋板而落入下部中。10‧‧‧殼體20‧‧‧誘捕滾輪30‧‧‧昆蟲60‧‧‧掛勾
