you cant catch latias or latios in diamond/pearl. you can migrate latias and latios from emerald, ruby, sapphire. in case you dont know, you get latias/latios at the end of the game and the mother tells you what color(red-latias/blue-latios) the guy on tv says. the hard part is to find it. it randomly appears any where on hoenn.

After u beat the elite 4, you'll be at home, when u go down stairs, the t.v will be on and you'll watch it with ur mom, it reports a Pokemon flying around. You get to choose the color u think it is. If u say the color is blue, then u can catch a latios. It is wild and is running like mesprit. If u say red, then latias will be available to catch.
The only way to obtain a Latias in Pokemon Diamond is to have it migrated. Latias is not a Pokemon that is encountered naturally in that particular game. The only game that does have Latias is Sapphire version (which can trade to other games, respectively). Thus, to have a Latias in your game, you must either use a cheat code or migrate it and re-capture it in the Pal Park.
To get any Pokemon from a previous version, you must trade it using the dual slot function of the DS. This can be done using a special park in the game with Ruby, Sapphire, Emerald, Fire Red, and Leaf Green. Alternately, you can use cheats that you can find on the internet.

Pokemon ruby/ sapphire/ emerald= latios/latias. Pokemon diamond/pearl/platinum=cressila.
Yes you can. later in the game Latias (or latios depending on which game you have) is attainable. Like mesprit in Pokemon diamond and pearl and like mesprit, latias and latios tend to flee.
