Red spots
What are those red spots above the leg? Looks like eggs of some kind??

 
I think they are immature mites.
Many beetle species have hitch-hiker mites that depend on the beetles to get them to new habitats and food sources. Although I'm sure some mites are very beetle-species specific, I've noticed some mites that get separated from their beetle will board another beetle species in a pinch.

I don't know what benefit mites could provide for a longhorn beetle but they are considered helpful to dung and carrion beetles because they reduce competition for the beetle larvae from fly larvae by eating fly eggs and newly hatched maggots.
