Aphid

Aphid

6039   There are lots of these bugs all over our cedar deck and wood patio door trim. A couple days ago they were a pale lime green and now they look like this. Not sure if they are termites or not. Also, the pine tree over the deck has seemed to spray down some sap over the past couple weeks not sure if that is related. We live in Toronto, Canada. 

This is an aphid, also known as a plant louse (Hemiptera/Sternorrhyncha: Aphididae). When feeding, they often secrete a sticky fluid called honeydew; this might be the ‘sap spray’ that you noticed. Ed Saugstad, retired entomologist; Sinks Grove, WV.
