The Carnivorous Plant FAQ Field Trip Report -

Massachusetts and Vermont in 2006

Return to the Trip Overview

Here, stranded, is a younger larval Wyeomyia smithii.

This insect, along with Metriocnemus, helps digest the prey in the pitchers. Recall that Sarracenia purpurea pitchers produce enzymes for only their first few weeks. After that, they rely upon bacteria and these arthropodal commensals to digest the prey.

Studies suggest that even though Metriocnemus is carnivorous, it does not attack Wyeomyia. Meanwhile it will attack and consume non-native mosquito species. Interesting, no?
