Fig. 13a. — The bog butterfly, Heodes epixanthe (B. & L.).

 and is mistaken commonly by growers for a spanworm moth. It is prac- 

 tically harmless.

No real cranteriy pest ever rests with its wings held up so. Other 

 kinds of butterflies, all with this habit, are common at times on many bogs.

A harmless moth common on many bogs, especially from May to mid- 

 July. It often excites suspicion.

 single conspicuous white stripe along the middle of each fore wing.

 coloration.
