Blooper

When the spelunkers are going through the "egg chamber", a giant "queen beetle" shows up, and it's suggested that killing the queen will throw the nest into chaos. The problem with this is that queens only appear among social insects, such as ants, termites, bees and wasps. Beetles are scavengers, not social, and even the isolation suggested in this movie would not produce a queen-based communal structure. Scavengers compete for food; they do not co-operate.
