No, Vesperlark has long since left the battlefield by the time Elenda enters the battlefield. They actually chill in the graveyard together for a while.
Let's assume that no one ever does anything, each break is a passing of priority
You Evoke Vesperlark, it is on the stack
It enters the battlefield triggering its sacrifice effect.
You sacrifice it, it enters the graveyard causing its ability to trigger so you choose Elenda as the target.
The ability is on the stack
Elenda now enters the battlefield.
If I bring back Elenda, the Dusk Rose with Vesperlark's Evoke, does Elenda, the Dusk Rose get a +1/+1 counter due to the sacrifice of Vesperlark ? I'm not sure since Elenda enters the battlefield as Vesperlark is leaving.
