Hi Claudia, the sap on this amur maple is not very sticky and none of the insects I watched seemed to have any problems, nor have I noticed problems on other trees with running sap, but that doesn't mean it might not sometimes occur. However, I do see these guys and many of the flies, landing nearby and cleaning themselves periodically. Christine

Great photo Christine. Seeing that little fellow standing in the sap makes me wonder if they somehow clean off their sticky little feet after eating. Or if they ever get stuck in it.
