Ecology
Hickory is used as a food plant by the larvae of some Lepidoptera species. These include:
- Luna moth (Actias luna)
- Brown-tail moth (Euproctis chrysorrhoea)
- Coleophora case-bearers, C. laticornella and C. ostryae
- Regal moths(Citheronia regalis), whose caterpillars are known as hickory horn-devils
- Walnut sphinx(Amorpha juglandis)
- The bride (nominate subspecies Catocala neogama neogama)
- Hickory tussock moth(Lophocampa caryae)
The hickory leaf stem gall phylloxera (Phylloxera caryaecaulis) also uses the hickory tree as a food source. Phylloxeridae are related to aphids and have a similarly complex life cycle. Eggs hatch in early spring and the galls quickly form around the developing insects. Phylloxera galls may damage weakened or stressed hickories, but are generally harmless. Deformed leaves and twigs can rain down from the tree in the spring as squirrels break off infected tissue and eat the galls, possibly for the protein content or because the galls are fleshy and tasty to the squirrels. The pecan gall curculio (Conotrachelus elegans) is a true weevil species also found feeding on galls of the hickory leaf stem gall phylloxera.
The
Evolutionary history
The oldest fossils attributed to Carya are Cretaceous pollen grains from Mexico and New Mexico. Fossil and molecular data suggest the genus Carya may have diversified during the Miocene.[9] Modern Carya first appear in Oligocene strata 34 million years ago. Recent discoveries of Carya fruit fossils further support the hypothesis that the genus has long been a member of Eastern North American landscapes, however its range has contracted and Carya is no longer extant west of the Rocky Mountains.[10][11]

Some fruits are borderline and difficult to categorize. Hickory nuts (Carya) and walnuts (Juglans) in the Juglandaceae family grow within an outer husk; these fruits are sometimes considered to be drupes or drupaceous nuts, rather than true botanical nuts. "Tryma" is a specialized term for such nut-like drupes.[16][17]

Hickory is sometimes used for wood flooring due to its durability and character.
An extract from shagbark hickory
The nuts of some species are palatable and were used by Cherokee Indians in making Kanuchi soup, while others are bitter and only suitable for animal feed. Shagbark and shellbark hickory, along with pecan, are regarded by some as the finest nut trees. Pecans are the most important nut tree native to North America.[4]
When cultivated for their nuts, clonal (grafted) trees of the same cultivar cannot pollinate each other because of their self-incompatibility. Two or more cultivars must be planted together for successful pollination. Seedlings (grown from hickory nuts) will usually have sufficient genetic variation.
