Spiders on Plants in Montana: Predators, Not Plant Pests

Southwestern Montana: black spiders with white spots, jumping spider size, slow, don't jump, "crunch" when squished. Web on plant tops with black deposits (eggs/feces). Aspen died; now on lilies (3 of 10 yellowing). Nursery and mother's same experience—plants die where spiders live.

Critical Fact

All spiders are predators. They don't eat plants. They likely protect plants by eating actual pests.

Real Problem

Something else is killing plants (root disease, watering, soil, other insects). Spiders are coincidental.
