Red is for danger
Milkweed bugs gather in a large multi-instar group, their bright coloring a warning to predators that they are poisonous. I don't know what the large brown bug under the cross-beam is, though.

up in north dakota they call these box elder bugs. at least the 'older' looking ones with darker coloring and the red appearing as stripes. the outside of a house might be crawling with them on a bad year -- patches the size of a door, blackened with the annoying creepers.
they were pretty much harmless but occasionally you'd feel a bite on the back of your neck or some other sensitive area where a bug had enough time to start some trouble.
The black ones are the adults; the others are younger stages (instars) of maturity. Milkweed bugs go through 4 instars, I think.
