Ants in your house or yard: September 2011 Archives

I took pictures of 2 Guardian Ants working Woolly Aphids. I am trying to find the name of the ant species that is acting as guardian to this mass of Woolly Aphids, Prociphilus tessellatus, on a growing Alder shrub next to a lake.

The area this Speckled Alder is growing in is very sparse during the winter with snow and ice licking at its branches. Where would these ants keep these aphids over the winter? Do aphids, and ants have sort of anti-freeze in there system that kicks in during the winter?

Since this was on a lake shore, and at the end of a wooded hill to the lake, do I need to be concerned relative to my plants about 500 feet away? If so what do you suggest?

Thank you,
Richard and Meghan

Dear Richard and Meghan,

Thank you for contacting AntBlog and send such nice photographs. This certainly helps with identifications. Since you are in New England, we reached out to an expert in the area, Stefan Cover, for help. Here is what he said:

"Those ants are Camponotus noveboracensis. The Camponotus are frequent aphid tenders but we know nothing about the relationship between these ants and that particular aphid. No need to worry about plants 500 feet away, though."

In addition, if you would like to read more about what ants do in the winter, please see our previous post here.

Best regards,
Stefan Cover (guest expert), Corrie Moreau & the AntAsk Team
