Data and code from: Body oscillations couple with wing flapping to reduce aerodynamic power in wild silkmoth flight

The data includes 3D kinematic recordings and wing and body morphometrics from 9 specimens across four silkmoth species during forward flight. The dataset enables investigation of how coupled wing and body movement affect aerodynamic forces and energy efficiency in silkmoth flight. It also supports phase relationships between body pitch and wing sweep that enhance lift and thrust while reducing power requirements. Details of each folder in the repository are as follows: Individual kinematics data (A. io: 4 wingstrokes; A. luna: 3 wingstrokes; A. polyphemus: 2 wingstrokes; H. euryalus: 4 wingstrokes) are stored in the folder 'Data_kinematics_individuals' and presented as Fourier fit coefficients in .mat files. Averaged representative kinematics data are stored in the folder 'Data_kinematics' and presented as Fourier fit coefficients in .mat files. Individual morphometrics data (A. io: 3 specimens; A. luna: 3 specimens; A. polyphemus: 2 specimens; H. euryalus: 1 specimen) are stored ..., , # Data and code from: Body oscillations couple with wing flapping to reduce aerodynamic power in wild silkmoth flight
