The leftover locusts again regrouped and the swarm divided into three groups, one of which moved towards Gurugram, and from there to Faridabad and onwards to UP. Another locust swarm moved towards Dwarka in Delhi, from there to Daulatabad, Gurugram, Faridabad and this swarm has also entered UP. The third group was seen in Palwal (Haryana) and has also moved towards UP. As of now, no locust swarms are spotted in any city areas.
