Leaffooted Bugs: Bugs all over my Yucca Plant

Their movements were in slow motion so I almost didn't notice the brown and red shapes on the yucca pods adjacent to my deck.

Leaffooted Bugs - the red ones are nymphs

In the enlarged photo above, the leaf shape of the hind leg is visible. These bugs are known for emitting a foul smell when disturbed. They suck plant juices. 

The activity on the yucca pod resembled more of a family reunion than a feeding frenzy. If the individuals moved at all, it was very slow.
