Myriads of Moths. — Kensington, (Philadelphia) was invaded last 

 night (July 9, 191 1) by myriads of a small species of moth or "mil- 

 ler," which swarmed in the streets and stores so thickly that business 

 and even traffic was for a time suspended. 



They flew so thickly in the streets that hundreds of pedestrians 

 took refuge in the stores along Kensington and Frankford avenues 

 and the streets running between them. They then began to fly into 

 the stores, and at the lights, so that merchants had to close their 

 doors and discontinue business while they secured brooms and swept 

 out the dead ones. 



In many places the sidewalks w'ere covered to the depth of an 

 inch for a block or more, and by getting into the eyes, nostrils, ears 

 and mouths of pedestrians the little "millers" almost completely 

 stopped traffic. 



A Second and Ritner streets trolley car was completely held up. 

 Without any notice a vast company of the "millers" swarmed through 

 the open window on the front platform, blinding and choking the 

 motorman, and doing the same for the passengers and conductor.
