Figure 2. Photographs of typical An. stephensi females when released in groups in the presence of either live (A) or dead-sporulating (B) H. subflexa caterpillars.

Following attraction to the caterpillars, the females land and probe them, sometimes engorging on caterpillar haemolymph (unpublished data). A) A healthy, uninfected H. subflexa 4^th-instar caterpillar. B) Several dead, sporulating H. subflexa caterpillars that had attracted An. stephensi females.
