Lepidoptera Spreading Boards can be made with a laser cutter, and some other tools. These boards normally have top layers that are made from basswood, which is soft enough to hold the necessary pins, but also durable enough that they can be used for years. The boards tend to be adjustable, so that they can hold different sized butterflies. For larger butterflies, such as those that have wingspans of up to 297mm, oversized boards can be used.

Key Takeaways:

• The top part of the Lepidoptera spreading board is basswood, because it isn’t too soft, but is still durable.
• If you find a Lepidoptera that isn’t big enough to fit on a number one size pin, a minuptin pin can be used in its place.
• In terms of tools you need in order to make a Lepidoptera spreading board, one thing you need is some type of sharp cutting tool.

“Lepidoptera with bodies up to 20mm thick and wingspans up to 130 mm can be spread with the regular board.”
