I think they are probably beneficial. They are very camera shy.TY
What are these and did they just hatch out
I looked at this weed more carefully and noticed aphids were on it. Do assassin bugs eat aphids?
Yup...and they think aphids are great snacks too...grin
There also is a good chance that these could be young nymphs of a leaf-footed bug (family Coreidae), as I can see at least two later instar coreid nymphs in this image. Some nymphal coreids are very similar in appearance to assassin bugs at early stages in their development - see http://farm5.static.flickr.com/4141/4933212356_c5b9e87d75.jpg for an example.
I was looking at the bug at the top right of the page....I thought the black spots were identifiers for Gminatus australis....do coreid nymphs have the spots also?
Flapdoodle, not questioning your expertise here, but my understanding of characteristic markings.....

@themoonhowl - The dorsal markings on some coreid nymphs - see http://farm5.static.flickr.com/4141/4933212356_c5b9e87d75.jpg and http://bugguide.net/node/view/534554/bgimage for examples - can be quite similar to those of the assassin bug nymphs you looked at.
Ahhh...those sneaky devils....thanks for clearing that up.
There are leaf footed bugs around, a lot of them, and they ruin sunflowers and tomatoes. I wonder why they would be congregated on this sickly weed though. The weed must look sickly because of the aphids. I did not see these orange nymphs piercing the plant as I have seen adult leaf foots doing sunflowers.I am going to try for a better picture today, if they are still there.
