Real Life Pokémon!! Also Looking For The Name

I found these insects in the backyard of my aunt's house, back in 2018, when I was taking some photos . With a camera in hand I take this picture and uploaded to EyeEm, a social network for photographers.

Here is the picture with some zoom:

As you can see, these pokémons come with 3 pairs of legs and spikes on the abdomen. I remember that they are mostly white with black dots, but some have a reddish orange hue.

If you know the name of these insects please share it with a comment and put an end to this old mystery of mine.
