What's eating my heliamphora minor?

Heliamphora minor is a sun pitcher from the Venezuelan tepuis, grown indoors in cool, humid, brightly lit conditions. Its pitchers trap insects passively. Fungus gnats exploit the wet, mossy medium. Mealybugs occasionally colonize the rhizome. Because Heliamphora is slow-growing and intolerant of temperature stress, pest damage can take months to show, then months to recover from.

Larvae damage roots and the rhizome in the sphagnum medium; plant growth stalls; pitchers wither prematurely Apply Bti drench; maintain cool temperatures to slow gnat lifecycle; use yellow sticky traps; top-dress with washed perlite

White waxy residue at the crown, between pitcher bases, or on roots; slow decline over weeks Remove with alcohol-tipped cotton swab; bare-root inspect and repot into fresh washed sphagnum if needed

Fine pale stippling and webbing on pitchers in warm, dry rooms; pitchers fail to fill properly Significantly raise humidity; improve airflow; spray surroundings with water; insecticidal soap as last resort
