wood ant

MacCook often observed the same fact later, among, with others, the already described Pennsylvanian wood-ant.

The Wood Ant (Formica lignipeda) is another familiar species.

It was a gigantic angry wood-ant, which hung on to my finger for all it was worth.

He discovered, also, what old stumps to tear apart when he wanted a pleasantly acid tonic dose of the larvæ of the wood-ant.

Formic acid is shed so sensibly by the wood Ant, Formica rufa, when an Ant-hill is stirred, that it can occasion an inflammation.
