Hi Lakpo,

The butterfly with the tailed hindwing is a species of fig blue in the genus Myrina (Lycaenidae), the larvae feed exclusively on figs Ficus spp. and have nothing to do with maize at all. The moth however looks like a species of Chilo (Crambidae) which are notorious pests of maize (search forChilo partellus)

Cheers,

Dave

Dear Koku, 

Insect Nr 1 is the stem borer, Chilo aleniellus (Strand) (Lepidoptera, Pyralidae) commonly occurring in West Africa and a pest of maize.

Insect Nr 2 displays Myrina silenus silenus Fabricius (Lepidoptera, Lycaenidae). Larvae of this species develop on trees of the genus Ficus (Moraceae). The butterfly is widespread inWest and Central Africa extending to Uganda and Sudan.

I hope this helps

Georg
