Ambush Bugs by Vicky Spelman

They are predators of others insects, even the occasional spider.  Like their name implies, they lie in wait on plants and capture prey that comes within range by injecting paralyzing saliva through their piercing-sucking mouthparts.  Almost always found on flowers favoring yellow and white flower heads, they wait for passing flies, bees and wasps that visit.   Greater numbers can be found later in the season.
