I assume that you mean that these little guys are all over your plants, correct? It sort of sounds like you are seeing them on top of the soil.

This is the larval stage of the Asian Lady Beetle, considered a most beneficial insect in the adult AND larval stages (until the adults swarm the inside of your house). They feed on small, soft-bodied insects and their eggs.

I agree with Rhizo 1. "Tons of these all around one of my beds" suggests that you may have a massive infestation of aphids or similar insect on one particular plant spp. You may have a glorious opportunity to demonstrate the effectiveness of the IPM tool box.
Cultural, manual, mechanical, biological, chemical. Help the helpful little brothers to help you by holding off the application of ANY control product in your yard. If you determine that the infestation is getting out of hand, choose a practice from another section of the tool box. But above all, observe, scout, watch from day to day and interfere/intervene only when absolutely necessary.
If you have a camcorder you can make quite a SF/Horror movie featuring invasion of the Axrydians.
Finally, 'Google' [Asian lady beetle infestation of structures], and read of the possible consequences of IPM. It should not deter us in the effort but heighten our awareness of the fragility of the total environment.
Thanks for my time on the soapbox.

I agree that this is the larval stage of a ladybug, but cannot determine whether or not it is actually the Asian ladybug.

Trust me....it's the Asian Lady Beetle. ;-) Though the many other species have larvae with a similiar appearance, it's still pretty easy to tell the difference.

Lucky you!
