Ant-nest Scydmaenine
A tiny, blind, pale yellow scydmaenine rove beetle found exclusively in ant nests. Its reduced eyes and pigmentation indicate a highly specialized subterranean lifestyle among ants.
Did You Know?
This beetle's pale, eyeless form is a classic example of convergent evolution with cave-dwelling organisms, achieved through adaptation to permanent darkness in ant nests.
Striped Seedcorn Beetle
A small, pale brown ground beetle with darker stripes on its elytra. It is sometimes a minor pest of germinating corn and other crop seeds, though it also eats many weed seeds.
Did You Know?
While it occasionally damages germinating crop seeds, studies show it consumes far more weed seeds, so its net economic impact on agriculture is actually beneficial.
