The above is a Velvet Ant that I was (bug nerd that I am) very excited to see yesterday! This crazy creature is actually a wingless wasp with an especially painful sting. This female is known to have one of the most excruciating stings in the world and backs it up with the red color and the nickname - the Cow Killer! This inch long insect is facetiously said to sting painfully enough to kill a cow! At least with the bright red color she exhibits aposematic signals that alert predators to avoid the potentially harmful sting.
The next harmful critter doesn't even usually give us the helpful bright color warning as she is usually solid black except for the red hourglass on the underside. This one in particular is very exceptional though. This venomous neurotoxin toting Black Widow spider can potentially (very rarely) kill a human and has markings on her back ...
And they seem to be hearts ...
... I told you that you'd get that warm fuzzy feeling.
(I did not find her in Shenandoah)
Now it's time for a real warm fuzzy...
