I had one caterpillar that had secured two S. leucophylla pitchers together with silk, created an abode under the lids, and proceeded to munch the softer tissue of the lids on both. Since the pitchers face away from my typical vantage point I didn't notice anything odd until I realized that the pitchers refused to separate when I attempted prying them apart. Since both the pitchers were damaged by the perpetrator I figured they wouldn't mind sharing once I had terminated the it...
In other news, one year I had an infestation of some sort of tiny grub in my D. capensis collection that absolutely tore up the plants - crowns, petioles, laminas, flower stalks, everything. They enjoyed boring holes into the plants' crowns right below the soil line to hide there. It took submerging the plants completely for a week to completely get rid of them - luckily D. capensis is bulletproof so they mostly all bounced back.
