The HOPE British insect collection includes specimens from the early 19th century to the present day. This means that some are very old and delicate. Of course, all of the insects are very delicate and easily damaged. Just think about the width of the legs or antennae of some of the insects you have seen in your garden! Not much more than a hair’s breadth! It isn’t surprising then that some of the specimens are showing their age and some are damaged.
In this post, learn how Tom Greenway, Junior HOPE Collections Assistant, repairs the damage and what happens to the bits that can’t be stuck back on!
“It’s always sad to see a damaged specimen but with a little bit of patience, and a mix of PVA glue and distilled water, we can make repairs to get them looking like new again!”

It isn’t unusual for the abdomen to fall off, as you can see here! Watch this video to see how we repair specimens.
Sometimes specimens will build up verdigris; a bluish-green crust made by a chemical reaction between the old pin, the insect and oxygen. We use a small brush to lightly remove it. Pins sometimes become rusty or damaged need to be replaced. For that job we use special stainless steel entomology pins.
Any parts that may have fallen off, but can’t be assigned to a particular specimen, are collected and stored in a gelatin capsule. This can be useful for any researchers looking to analyse DNA. The capsule gets pinned at the end of the specimen drawer so that it is kept with the correct species.
