Hunt for the Blue eared kingfisher !

This kingfisher looks almost the same as the common kingfisher Alcedo atthis . The differences is the blue ear coverts, darker and more intense cobalt-blue upperparts with richer rufous under parts.

While waiting for the kingfisher to come out of it's nest, I took some photos of the Common Greenback.

 Any ID for this caterpillar like stuff...?
