2014, Day 167 - Maracas

We found these butterflies in Mexico while following a cracking noise.  Crack, crack, crack in rapid succession.  It turned out that these were the culprits and I think they might have been calling their brethren to this tree.  Out of small wounds was leaking a red sap that butterflies and bees were eagerly ingesting.  I suspect there was a high sugar content but it was an interesting discovery.
