It forages in the undergrowth in the shade of dense forest canopy where it makes aerial forays to capture insects.

In poor lighting and within the Palni Hills it can be confusable with the white-bellied blue robin, which however has longer legs and is more likely to be seen on the ground.

[2][3][4][5] The white-bellied blue flycatcher occurs in dense forest and sholas south from Mahabaleshwar[6] through the Western Ghats, extending into the Nilgiris and the Biligirirangan Hills,[7] down to southern Tamil Nadu and Kerala.

[3] The white-bellied blue flycatcher tends to be quiet and inactive, foraging mainly in the dark shade below the forest canopy.

The song is a rambling series of rising and falling broken notes interspersed with clicks and squeaks.
