"Young males in the early summer may be quite small and easily overlooked..."

...Sounds like my early teens.

After some intense research (two and a half minutes on Google), I found out that the spider in the post below is called misumena vatia, a kind of crab spider, otherwise known as a flower crab spider or a goldenrod crab spider, because it can change its color from white to yellow to hunt in the sprays of yellow goldenrod flowers common in North America in the autumn.

Neat!
