Our walnut trees are having a good crop this year, and they are beginning to drop. Black walnut, Juglans nigra, are wonderfully delicious, though it takes some work to extract the nut. The genus name Juglans means "Jupiter's testicles," but I don't know where that comes from. 🌏

Fox squirrels (Rodentia: Sciuridae: Sciurus niger) are the largest tree squirrels in North America. Their diet consists largely of tree nuts and seeds, which they stockpile for winter. This individual was collecting black walnuts (Juglandaceae: Juglans nigra). Side Cut Metropark, Ohio, 14 Oct 2012.

Most treehoppers are very host-specific, feeding only on certain trees or shrubs. The nymph of this species (Hemiptera: Membracidae: Enchenopa sp.) was particular to black walnut (Juglandaceae: Juglans nigra). Blissfield Michigan, 14 Jun 2011.

Holy mother of Juglans

Easily the largest individual I’ve ever seen of Juglans cinerea, the Butternut!

This picture shows the compounded damage the trump kakistocracy is doing. Butternut, Juglans cinerea, is threatened by butternut canker, like this tree in Daniel Boone National Forest*. Weakening research and privatizing our federal lands will cause permanent damage.

* Tree is now dead
A woman, Barbara Morgan, in a blue sweatshirt stands next to a butternut, Juglans cinerea above a creek in Daniel Boone National Forest. The creek water is brown from spring floods, and fresh green leaves are expanding in the forest. Copyright Tom Kimmerer

Congrats to @jeffgroh.bsky.social et al on publication of "Ancient structural variants control sex-specific flowering time morphs in walnuts and hickories"

www.science.org/doi/10.1126/...
Science magazine front cover. Picture of a walnut in its opened shell. The text reads "All about timing. Mating type evolution in walnuts and pecans" graphical abstract: "In Juglans (top left) and Carya, two morphs show complementary temporal separation between male and female flowering (heterodichogamy). Mating types are controlled by two nonhomologous single-locus mechanisms that arose in the common ancestor of each genus, respectively. (Bottom left) Simplified schematic of a putative functional regulatory element at the Juglans locus. (Bottom right) Strong genotypic correlations across the Carya locus indicate a lack of recombination between two colinear haplotypes with similar gene content."

De #walnoot (Juglans regia) wordt wakker!! Deze mannelijke bloemen of katjes verschijnen in het voorjaar (april/mei) en produceren het stuifmeel om de vrouwelijke bloemen te bevruchten.

Walnut husk flies (Diptera: Tephritidae: Rhagoletis suavis) inhabit eastern North America. Females lay eggs in the fleshy outer husks of walnut fruit (Juglandaceae: Juglans spp.). The eggs hatch and the larvae eat the husk, but leave the walnut itself unharmed. Blissfield Michigan, 22 Aug 2010.
