Green-banded Broodsac infecting a snail

Leucochloridium paradoxum

Description:

A parasitic worm infecting a snail and causing it to seek an exposed spot during the day while pulsating it's green egg sack inside the snails eye stalk. All in order to attract a bird to eat it along with the snail so that it can complete it's life cycle. For a more detailed description see the second link in the references. And the videos in the link below show the pulsating movement of the worm inside the snail.

Habitat:

Found on some basil plants in my garden.

Notes:

Spotted this in the early morning, I snapped a few pictures before I had to leave. When I returned a couple hours later it was gone. I assume it was eaten by a bird. Higher resolution images and 2 videos can be seen here, https://www.flickr.com/photos/66454855@N...
