Help me find a game
 

Can someone help me find a game ?
I barely remember things about it.(I dont remember the age of they)
In this game you take the control of a ant in a brown square (I think a formicary)
you need to collect some yellow diamonds shapes there.
Is like an Pac-Man clone or something.
In the middle of the brown square there's an red gigant ant,she spred enemies,i think other ants on you.
She behave like the square where ghosts spawn in Pac-Man
You can dig other ways in the square just like Digger for the IBM.
It's not the MAXIS Sim Ant game
Have you ever seen this game ? is so important for me,it brings me so many memories of my childhood.
I re-create as much as i can the enviroment in paint.

Milipede? (1982 arcade game)

Or maybe Lady Bug?

Wait, Ant Eater? This matches most by description, but who knows.

I actually remember playing something that matches exactly that description, but I don't think I can be of much help. To add more info that of the original post, I think it was a Windows game, somewhere between Windows 95 to Windows XP, more probably XP. I feel it was one of those "Klik and Play" games, but I'm not sure.

Digger for DOS (1992)?
 

At first, I had thought that the game wanted could be the Pushover or its sequel named One Step Beyond, but they did not fully match your description.

I found a similar game, but would it by chance be called Digger? Here is one of the screenshots below:

If you'd like more people to chip in, you could ask people at r/tipofmyjoystick - they helped me on a couple of occasions finding old games.
