a dwarf alberta spruce is neither it is a needle
Spruce pines, Pinus glabra, have acicular leaves which are needle like.
Conifers are trees such as Pine and Spruce, with long and needle-like leaves.They keep their green leaves year round.
the function of long needle thread will direct in the long needle.

The cross section of the spruce leaf or needle is square in shape. The pine is flat. The spruce needle is attached singly to the branch on a short peg called a sterigma. Pine needles grow in clusters of two to six, depending on the species. See the related link for more information.
Spruce trees are more likely to survive in areas with extreme changes in climate because, spruce trees are equipped with a thick cuticle that covers their needle-like leaves. this waxy cuticle that covers each needle prevents water loss from spruce and pine needles. because of this they are able to survive in cold months, and drastic weather changes, because they do not have to worry about water loss, like other trees. if you have ever noticed, in the winter maple trees have no leaves on them because they are not protected for winter months, while spruce and fir trees needles are still on the tree and look fresh, and not harmed, because they cannot lose water, keeping them healthy all year long.

No. It's a softwood. The difference isn't a matter of wood density. Softwoods come from needle-leaf trees, and hardwoods come from broadleaf trees. The softest wood in the world is balsa, which is extremely soft and lightweight...but because balsa trees are broadleaf, balsa is a hardwood. On the other hand, Radiata pine is roughly as hard as mahogany - which is unquestionably a hardwood - but because it's a needle-leaf tree it is a softwood.
Spruce beetles are approximately 1/4 inch (6 mm) long, and 1/8 inch (3 mm) wide.
a spruce has clusters of 1 and their usually sharp. Pines usually produce 1 whorl of branches per year and have needle clusters of 2-5
Examples of needleleaf trees include pine, spruce, fir, and cedar. Needleleaf trees are characterized by their long, thin leaves in the shape of needles, which remain on the tree year-round. They are typically coniferous trees and are common in colder climates.
