Tiger moth Asotacaricae, widely present across Asia and the Pacific islands, can cause a toxic-allergic disease called lepidopterism. It can be mistaken for dengue or chikungunya because of similar symptoms, according to a study done since 2006 by Aster MIMS Research Foundation.
Without specific diagnosis, the actual, underlying disease can go unnoticed and worsen to acute, and even fatal, respiratory problem.
Period: June to August
In Kerala, these cases occur from June to August, when the moths flock to artificial lights in and around buildings, said senior scientist of the foundation, P.J. Wills, who led the study.
Tiger moth caterpillars forage on Ficushispida (commonly called hairy fig and “Paarakam” in Malayalam).
