How fish feed on it

Don't file this one with the dusk beetles above — it behaves quite differently. The manuka beetle falls through the day rather than at last light, a bright green beetle dropping steadily out of bush and scrub-lined cover on any warm afternoon from November into February, without needing a single dramatic evening to make it worth carrying. It's less an event to wait for than a dependable searching fly: the one to try when nothing else is hatching and you just need something to prospect the water with. Still earns a slot in the box — just for a different reason than its dusk-flying cousin above.
