This December, 68 larval samples were collected in the field by vector control technicians and identified by the lab. The most frequently occurring species in larval samples was Aedes washinoi, the woodland pond mosquito, found in 26 of the 68 samples. This seasonal mosquito species breeds in shallow ground pools filled by winter rains and overflows from rivers and streams. Culiseta incidens, the cool weather mosquito, was the second most frequent species found, present in 23 of the 68 samples. Both Cs. incidens and the next most frequently identified species, Cs. inornata, the large winter mosquito, are often found in ponds, containers, and other sources during this time of year.
