In this study, a fluid added mass effect on an insect flapping flight was evaluated numerically. The flapping flight of the model wing dynamically similar to that of Diptera was developed using our fluid-structure interaction (FSI) model proposed previously. Our computational FSI analysis validated here was applied to the model flight with three different wing masses, one of which gives the inertial effect dynamically similar to that of the dipteran insect, while the others of which give the ignorable inertial effect. It follows from the present results that the dipteran passive pitching motion and the lift force generation would be enhanced by the inertial force due to the wing mass.
