A reader wrote to us recently about some white and brown larvae with big round heads that she found in her room. By big heads, we mean that the larvae have heads that are large relative to their thin bodies; indeed, the thin bodies combined with the large round heads make the larvae look a bit like lollipops. The dominant color of the larvae is a light brown, but a segment of their bodies is white. The reader found about 20 larvae in her room, and despite extensive searching she has found nothing that looks like the creatures she found. Of course, she wants to know what is in her room, so she asked us if we know anything about the larvae with big round heads that she found.
