Zygopterans

  The one on the left approached about 6 inches in length… maybe a Pseudostigmatidae.

Saturniid eggs

I think these are Saturniidae eggs.

Army ants in La Selva

A caterpillar

I first though this glob on the underside of a leaf was an egg mass from a frog, maybe a centrolenid.  I took a picture, and it appears that there is a caterpillar in the center.  Is it alive?

Agitated ants

   

In Campanario, these ants patrol much of the forest.  When agitated, they move into a defensive position with their abdomen below them, pointed as a gun.  I know some ant do it, so I suspect they are capable of spraying formic acid at offenders.

Another skipper

Drosophiliidae

I have a few of these for you, Pat… and Dr. Foote.

He was squished

Family?

No luck

My soapy-water pan traps were not very effective.
