The bagworm caterpillar lives its entire life inside a tough protective case made of silk and camouflaging bits of foliage. Each caterpillar makes its own bag that it carries around as it feeds with the head and legs sticking out the open, top end of the bag. As the caterpillar eats and grows the bag is enlarged until by the end of the summer, what started as tiny pods only one-quarter inch long will have grown to almost two inches in length.
Common hitchhikers that do not harm the plants, but are commonly found in the pots of houseplants are sowbugs, millipedes, springtails and fungus gnats.
