Heliconius hecalesia formosa Bates 1866
Like its comimic H. hecale, H. hecalesia formosa is large and strong flying. It is rare at La Selva, being more common higher in the mountains where its preferred host plant P. lancearia may be found. This species may also use P. arbelaezii, but I have not seen this at La Selva. Like many other members of the erato-charithonia species group, hecalesia feeds and grows well on a range of other Decaloba species, including biflora, helleri and talamancensis. Range: Mexico to Colombia and Venezuela. I have no photos of the larvae.
