While I don't think the lemon tree means much of anything, I do think the swarm of butterflies foreshadow something terrible that's going to happen later this Volume... Well, considering Maria's name means "a sea of bitterness" in Latin, it could be a reference to herself, losing the will to fight after losing her eyes.

As for the blue butterflies, some feel they're referencing the blue catepillar from "Alice in Wonderland." We already had the two jabronies at the gate, who act like the Queen's guards, and Commander Cordovin being the Queen of Hearts, so to speak. Something like this anyway.
