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.
Spruce Gall Adelgid
A tiny woolly aphid-like insect that induces distinctive pineapple-shaped galls on Norway spruce twigs. The galls form when the insect's feeding causes abnormal growth of developing needles.
Did You Know?
The pineapple-shaped galls are formed by modified needles that swell and fuse together, creating chambers in which the adelgid nymphs develop protected from the environment.
