Raw Data for Fig. 2-6, Fig. S2 and Fig. S4 and R code of Moore Modified Rayleigh Test (MMRT) in the manuscript Bogong moths navigate using a light-dependent geomagnetic inclination compass by Chen et al. 2026.

The Excel files respectively show the raw data underpinning Figures 2-6 and Figures S2, S4 of the following manuscript:
Chen, H., Rosberg, L., Dreyer, D., Leberecht, B., Mouritsen, H., Fleischmann, P.N., Warrant, E.J. (2026). Bogong moths navigate using a light-dependent geomagnetic inclination compass.
The Excel files corresponding to Figures 2-6, S2 and S4 contain raw data used to generate the circular plots presented in these figures. The data detail the mean directions, r-values, standard deviations, and p-values of individual Bogong moths tested in a flight arena under various experimental conditions.
Figure 2A–C, Figure 4A & Figure S2A-D: Laboratory experiments with modified magnetic fields and light spectrum
Raw data for moths tested in the laboratory under conditions:
Geomagnetic field with azimuth at 0°, panorama-walled arena, randomized stars, full spectrum of stellar illuminationGeomagnetic field with azimuth at 180° , panorama-walled arena, randomized stars, full spectrum of stellar illuminationNulled magnetic field, panorama-walled arena, randomized stars, full spectrum of stellar illuminationGeomagnetic field with azimuth at 0°, panorama-walled arena, randomized stars, stellar illumination with light spectra>480nmEach dataset includes mean direction, r-value, standard deviation, and p-value for moths in each condition.
Figure 3A-C Bogong moths possess a geomagnetic inclination compass.
Raw data for moths flown through ABA test in the laboratory under:
Spring migratory moths were flown in a panorama-lined arena under a projected full-spectrum randomised starry sky and within a coil-generated natural geomagnetic field (NMF).When magnetic polarity in a was reversed by 180° without altering inclination.When magnetic inclination in a was inverted without altering polarity (via inversion of the vertical field component alone).Figure 4B–D: A single cohort of 56 spring-migratory Bogong moths maintain their inherited orientation using natural stellar cues in the absence of both a natural geomagnetic field and UV-blue light
Raw data for moths flown through ABA test in the laboratory under:
Nulled geomagnetic field, natural starry sky, full-spectrum illuminationNulled geomagnetic field, natural starry sky, restricted illumination spectrum that lacked UV-blue lightNulled geomagnetic field, natural starry sky, full-spectrum illuminationData present mean direction, r-value, standard deviation, and p-value for each condition.

Raw data for moths tested: In the field within transparent arenas enclosed by filters transmitting different restricted illumination: λ > 310 nm, λ > 380 nm, and λ > 480 nm.
Data include mean direction, r-value, standard deviation, and p-value for each experimental group.
