If I pass by the Swords of Justice, can I catch them later?

Question

In Black 2, I'm in Opelucid City. The place is frozen over, and I've beaten the Shadow Triad enemy. I have encountered, but not battled, Cobalion and Virizion, two of the Swords of Justice on the way here. If I progress further, will they disappear, or will I be able to come back and catch them later on?
If possible, avoid heavy spoilers, please. I don't mind being spoiled, if it gives me the knowledge I need, but it would be nice to have the rest of the game to be a surprise.

Answer 1

Yes you can.They stay there until you catch them. I caught mine way later

Answer 2

Yes you can
When you first meet them they will be at their respective levels that you meet them at first (45 for cobalion and so forth based on their routes) But if you beat the champion and gain the national pokedex they will be a higher level than before (for the cobalion example he gains 20 levels from 45 to 65) In fact my cobalions still sitting in its spot waiting for me as we speak.

when i caught them and i got the national pokedex and stuff and they were the same lv

Answer 3

yeah but they all will be at lvl 65 instead of 45 so they might be harder to catch.That is if you beat the champion,iris, first.Terrakion will be at route 22.
