Explanation:
The Bihar hairy caterpillar (Spilosoma obliqua) is a gregarious, sporadic, and polyphagous pest. It is commonly referred to as the jute hairy caterpillar because it is a serious pest of jute, although it attacks over 100 plant species.
Its caterpillars are known to cause defoliation and significant yield losses in crops like jute, sunflower, groundnut, and pulses.

Gregarious nature: The larvae move and feed in groups, especially in early instars.
Sporadic pest: It doesn't appear every season but can suddenly cause serious outbreaks under favorable conditions.

Host range: Very wide; includes vegetables, oilseeds, and fibre crops.
