The little spiderhunter (Arachnothera longirostra) is a species of long-billed nectar-feeding bird in the family Nectariniidae found in the moist forests of South and Southeast Asia.

[2] They are found near their favourite nectar bearing trees, often species of wild Musaceae or flowers in gardens.

[2] The genus name Arachnothera means "spider hunter" and the species epithet refers to the long beak.

Several other island forms are noted:[3] The species is found in Bangladesh, Bhutan, Brunei, Cambodia, China, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, Philippines, Thailand, and Vietnam.

[7] The nest is a compact cup attached under a leaf of banana or similar broad leaved plant.

The nest is hammock-like and suspended from the underside of a leaf using 150 or so "pop-rivets" of cobwebs and vegetable fibre, a unique method of using spider silk for animal architecture.

[20] In Sarawak, the Kayan, Kenyah and Punan people consider it a bird of good omen and when they are out collecting camphor, the men would wait until they heard the sit call of one of these spiderhunters.
