Please help with identify this bug

[tuidayne]

I have never see this bug in my life, it looks like a tiny beetle but I'm sure it's a beetle or something else.  It's very tiny about .4cm (1/8").  They crawl all over the cement walkway in front of my yard when the sun goes up.  I don't know where they come from (either the lawn or under ground).  Please see the photo, the red tubing in the photo is the water hole.

Thank you very much in advance for all your help.

These appear to be some sort of aphids. Please tell us where in the world your yard is, as it may help someone to identify them.

Thanks Adam,

I live in in California, south of Los Angeles county.  I live in this place for over 5 years and this is first time suddenly they appear in my front yards few days ago and they are still here.

I don't think they are aphids, because they are not on the plant or my flower bed and they have hard shell, they love to crawl up to the wall.

They are definitely aphids -

You can clearly see the "tubelike projections on the posterior, called cornicles or siphunculi" which are diagnostic as mentioned on the bug guide web page, in the second of your photos.

Presumably they have moved off whatever plant they were on and are looking for a new host. I am not familiar with general aphid behaviour, particularly half way round the world from me, but I expect there is a reason for the movement.

Thanks Adam and Livingplanet3, I will do more research and study on aphids. Yeah you're right, only aphids have cornicles similiar like the bug in my yard.
