Blooderflies

Yesterday, I learned that one of the fan-created monsters in Dungeon Denizens II is the "Blooderfly". 

I wonder if this will be similar to the "blooderfly cloud" from Silent Nightfall (Purple Duck Games 2013)?

Here is the text for reference (pp. 19-20):

Even the tiniest and most inoffensive creatures are affected by the demonic radiation, as the blooderfly clouds show.  These are clouds of pure white to pinkish butterflies which can surround a creature in order to feed upon its blood, flushing their wings to a bright red.  These creatures attack victims in swarms, occupying a 20’ x 20’ area, and each creature within the space must make a DC 15 Fort or Ref save to avoid taking 1 point of Stamina damage due to blood loss.  When the swarm has taken 10 points of Stamina, it disperses to digest.  Swarms take half damage from any attack that is not an area effect.
