Distribution Eastern India and eastern Bnagladesh, Burma and southern China (Yunnan Provences).
Systematics and txonomy Member of a speciose genus for which monophyly has not been confirmed.
Habitat Forests, or areas with adequate host trees or shrubs.
Biology In southern China host plants recorded by Yang et al (2013) included 31 species in 16 families and 24 genera. The most common host plant families include Myrtaceae, Verbenaceae, Oleaceae, Euphorbiaceae, and Mimosaceae. In addition to native hosts, E. signifer occurs in four species of introduced Eucalyptus.
Development in southern China usually takes one year. Adults emerge, mate, and lay eggs in April, and eggs hatch in late April or early May. Adult emergence begins in the late afternoon and peaks between 17:00 and 18:59 hours. Mating fights last under 30 min at dusk and the copulation lasts 24 hours.
Larvae initially live in forest litter for one to two months before moving into woody stems for the remaining ten months. Larvae start boring into hosts between June and November with most transitions occuring in July and August. References Tindale, N.B. 1941.
