The ugly larvae, part one

Like spittlebugs, tortoise beetle larvae conceal themselves underneath an excretion of the plant material that they eat.  However, since the beetle larvae feed on leaves rather than sap, the end product is not nearly as elegant as the spittlebugs'...

...nor is the process of making their coverings.

Yet regardless of aesthetic objections, the fecal shields seemed to be quite adequate for the purpose of protecting the larvae, which thoroughly infested the bindweed in the garden without attracting any predators or parasites (as far as I could see).
