LAHORE: A strange insect, less than the size of mosquito which had been witnessed almost everywhere in the City during the past several days, invaded the residents on Thursday night, forcing many shopkeepers to shut down their businesses. The middle picture shows a heap of dead insects after a shopkeeper ranked them out of his shop. The right picture shows humming of the insects around a light, while in the left picture, they are seen as close-ups.Staff photos by Abid Hussain
