The Lesser Striped Swallow has a rufous head and rump, dark blue back, and streaked white underparts. It catches insects in flight and builds a mud nest.
Adults have rufous-chestnut on the forehead, ear coverts, nape, and neck, with dark blue upperparts, a red rump, and white underparts streaked dark. Juveniles are duller and have shorter outer tail feathers.
It eats mostly flying ants, bees, flies, butterflies, and moths, as well as some fruit. It builds a mud nest with a tubular entrance, placing it in a cave, under a rock overhang, or on a branch.
