2.5. Diagnostic Notes **Identification is currently undergoing peer review as part of the National Diagnostic Protocols by SPHDS.**

Symptoms of mango web weaver infestation include; a nest of leaves woven together by silk, completely defoliated leaves leaving mid rib, dried shrivelled shoots and an absence of flowering and fruiting (Singh 1988).

Egg period between 4-7 days Larval period between 25-33 days; smooth and active; 5 instars; fully mature larva 25 mm long; 5 mm wide; pale grey with prominent white stripes on the dorsum. Pupal period between 8-45 days; pupate in silken cocoon and hibernate in the soil at depths of 8 – 10 cm

**Adult** wing span 31mm; body length 14mm; males are smaller than females; forewings grey with patches of white scales; hindwings grey colour with less patches of white scales; nocturnal fliers (Singh 1988). Under laboratory conditions, the adult female can lay up to 155 eggs and survive between 3-5 days.

The genitalia of _Orthaga euadrusalis _have not been described. I include genitalic photographs of both sexes for additional diagnostic purposes have been provided.
