I have a (portulaca grandiflora) Moss Rose plant in a container kept in the Balcony. It is infested with this worm like insects. they are many. I tried spraying insecticide bought from nursery but they seem unaffected. Please help me find what this worm exactly is and what it’s called so that i can find out proper killer for these creatures. They have affected the plant badly and flowering is reduced remarkably. Buds are drying our before blooming.
