It is obviously impractical to record observations of all the urban Aedes we find. The main goals of Mosquito Alert are to understand the current distributions of the species and discover the new areas where they appear. Therefore, if you don’t want to send all of your sightings, we suggest that a pair of sighting reports within a week for the same location is sufficient. If you see them repeatedly in the same place over a much longer period of time, a couple of reports per month is sufficient.
That said, in an ideal world it would be useful to have photos of all of the urban Aedes you see because this can help us study their population densities and phenology. This kind of data could also be very helpful when managing possible cases of arboviruses.
