Anopheles "
maculipennis complex" - unable to say which species from larval or adult morphology.

In my opinion An.claviger cannot be excluded without a detailed photo of the head. So Anopheles spec. it is.

Generally I find that 4th instar
claviger have a larger, more transverse central head spot, but I'm not sure that applies to younger larvae. As this one is only 5mm, I guess it could be an earlier instar, so we had best go with
Anopheles sp. :)
On the other hand, the fact that this is a newly-built pond suggests it may be as yet unshaded, [Ira can tell us] in which case I think
maculipennis complex is more likely to colonise. ;)

The pond is unshaded. There are no plants in the pond and only a few small plants around the pond.
