OF EASTERN PENNSYLVANIA. I I 5 



familiar species in New England, is according to 

 our experience, an occasional visitant in Eastern 

 Pennsylvania. In Southern and South-western 



j 



New Jersey it is more abundant. It makes its ap- 

 pearance at the earliest, from the i 5th to the 2Oth 

 of May, and lingers usually with us until the 5th 

 of June when it suddenly disappears. 



Its habits remind us of those of the ]\[niotUta 

 raria, in the facility wit 1 ! which it moves around 

 the trunks of trees in quest of insects; it is, besides, 

 an expert Flycatcher, capturing insects after the 

 fashion of the Wood Pewee. It is an active, rest- 

 less creature, seldom remaining any considerable 

 length of time in the same locality. 



The duration of their stay depends mainly upon 

 the abundance of insect-food. Though chiefly 

 denizens of low swampy woods and waste fields 

 overgrown with bushes and a few scattering 

 trees, during the greater part of their stay, they 

 sooner or later forsake these haunts for the habi- 

 tation of man, where in the adjoining orchards they 

 glean a ready subsistence. They now manifest 

 considerable tameness, and permit an easy ap- 

 proach. 



Their food consists oi the larvae and pupae of 

 insects which they obtain from creviced bark, 



\ * 



besides, mature forms of different kinds. Among 

 the latter, may be mentioned CJirysoinela ccerulci- 

 fciinis. L'ynrindis liridipcnnis, Bostriclnts />/;//, 

 Aphis inali, Apis mcllijica, Muse a domes tic a, Tab a- 

 nus lineola, Anisopteryx vernata, and others com- 

 mon to the season.
