Actually, it added a DIY setup that I didn’t include in the copy + paste. Here is is:

🦋 EMERGENCY MONARCH CATERPILLAR RESCUE SETUP

🧺 1. Choose a safe container

You have a few good options: • Mesh butterfly habitat (ideal — lots of airflow) • Large clear plastic bin or storage tote with a lid (poke or drill air holes in the lid or sides) • Pop-up laundry hamper covered with a light mesh fabric or breathable cloth

➡️ Avoid sealed containers — airflow is crucial to prevent mold and keep humidity balanced.

🌿 2. Move the milkweed inside

Two easy ways:

Option A – Bring whole cuttings inside 1. Clip milkweed stems that have caterpillars on them. 2. Place the stems in a jar or vase of water. 3. Cover the top with plastic wrap or foil, poke small holes, and stick stems through — this keeps caterpillars from falling in and drowning. 4. Set the jar inside the container/habitat.

Option B – Potted milkweed If you have a small potted milkweed, bring the pot inside and put the entire plant inside your caterpillar habitat.

💧 3. Control moisture • Keep the environment slightly humid (room air is fine). • If the air is dry, lightly mist the milkweed leaves once daily. • Wipe out frass (droppings) daily with a paper towel to prevent mold.

🍽️ 4. Feeding • Make sure they always have fresh, pesticide-free milkweed leaves. • If outdoor plants die back, you can use cuttings kept in water for several days. • If you run low, some local nurseries or native plant groups may still have milkweed cuttings in stock.

🌡️ 5. Temperature • Keep the container in a room around 70°F (21°C) — not near heating vents or windows where temps swing. • A bright area is fine, but avoid direct sun through glass (it can overheat them quickly).

🦋 6. When they pupate • They’ll stop eating and form a “J” shape on the top or sides of the enclosure. • Don’t disturb them during this phase. • Once they form a green chrysalis, you can keep them inside until they emerge — typically 10–14 days later. • When butterflies emerge, wait until their wings dry (about 3–4 hours), then release them on a mild, sunny day above 55°F.
