The Carnivorous Plant FAQ Field Trip Report -

Splinter Hill Bog, Alabama, 2010

Return to the Trip Overview

Pitcher portrait
It was early in the season, so Exyra damage had only begun. But as I composed this photograph I noticed something that I had been seeing all day long, but which just had not properly registered.

Look at the large, ragged holes cut in the pitchers.

What is doing this? A paper cutting wasp? I have seen such wasps in S. jonesii, as I reported on in a 2007 expedition. Was this the same thing?

Peering inside such damaged pitchers, I could see no larvae. Nor could I correlate this with the presence or absence of Exyra larvae or damage.

I still do not have a good answer.
