It's almost Valentine's Day, so let's hear what bugs you love the best. Bonus points if they're red, pink or heart shaped. Extra credit if you tell us in a poem.
Here's one of my favs, the Cardinal Meadowhawk, a common species in the Pacific Northwest and always glorious to see.

Two books in my personal library somewhat related to your thread: my copy of Photographic Investigations of Faint Nebulae by Edwin Hubble, his PhD dissertation, published in 1920, and the first French edition of Mary Sommerville’s On the Connexion of the Physical Sciences published in 1837.

Dwindling snow threatens Greenland's dogsled mushers' ancestral way of life.
Snow has become so scarce on Greenland’s east coast that even short dogsled journeys now break down, making the business of running dogsled tours increasingly economically unviable

The 'With These Hands' trail features plaster casts which reproduce artefacts from the Mohenjo-daro ruins, one of the great cities of the Indus Valley Civilization (3000-2500 BC). Sold as cultural souvenirs, these casts connect modern makers with disappearing histories.This seal was donated in 1955.

Pegmatite is a type of igneus rock that frequently contains large crystals of quartz, feldspar, or mica. When looked at with a longwave UV flashlight, these minerals seem to glow! Kids at our museum can see this for themselves up close and personal.
