These pins are good for more than entomology, be sure to check out our blog: 10 Things You Can do with Insect Pins.  Sizes 000, 00, 0, are thinner than acupuncture needles & can even be used as electrodes in neuroscience.

Black enamel or stainless steel? They are identical in sharpness, diameter & length but there are important differences.

The black enamel ones are made from spring steel & are coated with a rust resistant lacquer after they have been cut. For soft bodied insects this should be fine, especially for student use or if you are using them to ream out holes & then dispose. They are not recommended for hard bodied insects since the coating can scratch off & the pin will rust eventually.

The stainless steel ones can be used for all insects & applications whether they are permanent collections of insects or textiles or any other material that you don't want to be disfigured by rust.

Insect pins are handy for making pinhole cameras but results are very dependent on the diameter of the pin.

Here are some useful resources:

This is a detailed list of Insect Pheromones. For something completely different, enter some names into our 3D Molecular Model Builder. You can actually build the molecules but what is amazing is the range from very simple structures to very complex.

An excerpt from the USDA Guide for Insect Pinning (no longer on-line) had these suggestions:

In section 3.1 - Preparing Dry Specimens for Mounting, the guide discusses some basic insect preparation:

"Any dry insect that is to be pinned must be relaxed.... a relaxing chamber usually will make this procedure much easier."

To this end, we offer a simple solution involving petri dishes & filter paper. All you need is to put some sort of support under the filter paper.
