Explanation of Names
From French ├ęclosion originally from Latin e (ex) out of, plus clausus shut.
eclosion noun, verb to eclose
1 - the process of emergence (hatching) from the egg
2a - emergence of the adult (imago) from the pupal case (insects with complete metamorphosis)
2b - emergence from the skin of the last instar (insects with incomplete or gradual metamorphosis)

Photos showing eclosion:
The word eclosure shows up only on a couple of web sites in the context of entomology--usually it shows up in other contexts is a misspelling of enclosure. The word eclosure does not seem valid--it appears to be a spelling error for eclosion. Gordh, A Dictionary of Entomology (1), has no entry for eclosure, but has one for eclosion.
