Ultimate Guide: How to Preserve Butterflies Step-by-Step

Preserving butterflies can be a rewarding hobby, mixing the joys of entomology, art, and science. This step-by-step guide will teach you how to properly preserve butterflies, ensuring their beauty lasts for years to come.

Materials You’ll Need

Before you start preserving butterflies, gather the following essential materials:

• A butterfly net
• An insect killing jar or freezer
• Small envelopes or parchment paper
• Butterfly spreading board
• Pins specifically designed for entomology
• Labeling materials (pencil, paper, etc.)
• Sealable display case or glass frame

Step 1: Capturing Your Butterfly

Using a butterfly net, gently capture the butterfly you plan to preserve. Capture the butterfly with **minimal handling** to avoid damaging its wings and delicate body. Gently guide the butterfly into the killing jar or carefully place it in the freezer for 20-30 minutes until it’s humanely euthanized.

Step 2: Relaxing the Butterfly Specimen

Once the butterfly is euthanized, it often becomes brittle and hard to manipulate. To prep it for preservation:

• Place the butterfly in a relaxing chamber, which can be as simple as a sealed container with damp paper towels at the bottom.
• Leave it in the chamber for 12-24 hours, allowing the moisture to soften its body and wings for easier positioning.

Step 3: Spreading the Butterfly

Now that your butterfly is relaxed, you can proceed to **spread its wings** for preservation.

Choosing a Spreading Board

Use a butterfly spreading board designed to position the wings at the correct angles. These boards often have adjustable slots for different wing spans.

Pinning the Butterfly

• Place the butterfly in the slot, ensuring the body is even with the board’s surface.
• Insert a pin through the center of the thorax, avoiding damage to crucial parts of the butterfly.
• Using additional pins, secure the wings in a spread position, ensuring they are symmetrical.

Step 4: Setting the Butterfly

Leave the pinned butterfly on the spreading board in a dry, airy location for about **2-3 weeks**. This drying period ensures the butterfly fully sets in its spread position, preventing any deformation or degradation.

Step 5: Removing the Butterfly

Once fully dried, carefully remove the pins, starting with those securing the wings. Gently lift the butterfly from the spreading board, handling it by the thorax or using tweezers.

Step 6: Mounting the Butterfly

Mount the butterfly in a display case or a glass frame. Ensure the display case is sealed well to protect the butterfly from dust, moisture, and pests.

Labeling the Specimen

Include essential data such as the species name, location of capture, and date. Proper labeling not only makes for an attractive display but also adds scientific value to your collection.

Tips for Long-Term Preservation

Preserving butterflies is an ongoing process. Follow these tips to maintain your collection:

• Monitor for pests: Periodically check for signs of insects that could damage your specimens.
• Control humidity: Moisture can lead to mold growth. Keep your display cases in a cool, dry location.
• Limit light exposure: Extended exposure to sunlight or artificial light can fade the butterfly’s colors.
• Gentle cleaning: Use a soft brush to remove dust from the wings and body occasionally.

Conclusion

Preserving butterflies is a meticulous but rewarding task that allows you to appreciate the delicate beauty of these insects. By following this step-by-step guide, you can create a stunning collection that stands the test of time, combining both artistry and scientific curiosity. Whether you’re a hobbyist or a dedicated entomologist, these methods ensure your butterflies are preserved in their full splendor.
