Biology. This species causes a gall on Apluda mutica L. ( Poaceae) described simply as a leaf sheath gall by Felt (1920) from India, but later extended by DvLR & Dvl (1926, gall No 52, Fig. 28 [Fig. 26a]) who found it on the same host in Indonesia. The gall protrudes from the sheath of the youngest leaf. The leaf blade remains undeveloped. The sheath is shaped into a tube enclosing and supporting the growth tip. The gall grows out of the older leaves and buds which develop after the infection and are long and thin, with a slender apex.

Geographical distribution. Orseolia apludae was collected and reared at Coimbatore, Tamil Nadu, India, 1-i-1917 (Felt 1920). The galls were found in Indonesia in Salatiga, Java, alt. 600 m, vi-1909 and Kamal, Madura Island, v-1910 (DvLR & DvL 1926) .
