During the months of the summer period, the adult female who had already indulged in a mating process, chews around 35 to 90 depressions into the bark of the host tree, and then lays eggs in every pit. Most of the eggs hatch within 10 to 15 days.

Signs & Symptoms Your Trees Are Infested with ALB
According to the United States Department of Agriculture, signs of ALB infestation “start to show about 3 to 4 years after infestation, with tree death occurring in 10 to 15 years depending on the tree’s overall health and site conditions.”
What You Can Do To Stop the Spread of ALB
In order to stop the spread of these invasive pests, homeowners should have the trees on their property inspected annually by a certified arborist, especially if you have noticed any of the signs listed above. Learn about the quarantines that currently exist in your area.

Adult beetles feed on leaves, twigs and young bark. Females deposit anywhere from 35 to 90 eggs, one at a time, in pits they dig in the bark. When the eggs hatch, ALB larvae bore into the cambium, the tissue that ferries the tree's nutrients, and then they move into the heartwood.

What is the threat of Norway maples?
When the culprit was identified, and the USDA realized the nature of the threat—a beetle with the capacity to destroy numerous native hardwoods—the agency began cutting down thousands of infested trees and chipping them. That's the best way to ensure the beetle's demise; insecticides don't reach it once it has burrowed past the cambium, although they might protect unafflicted trees. In addition, the USDA established a quarantine around much of New York City, prohibiting anyone from transporting wood that could host the beetle. The restriction is still in place. In the 13 years since the initial outbreak, authorities have documented the ALB in Queens, Staten Island, northern New Jersey and on Long Island. The work of eradicating the beetle from the New York City area continues.

Overview
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short (e.g., Neandra brunnea) and such species can be diffi…
Description
Other than the typical long antennal length, the most consistently distinctive feature of the family is that the antennal sockets are located on low tubercles on the face; other beetles with long antennae lack these tubercles, and cerambycids with short antennae still possess them. They otherwise vary greatly in size, shape, sculpture, and coloration. A number of species mimic ants, bees, and wasps, though a majority of species are cryptically colored. The titan beetle (Titanus gig…

Classification
As with many large families, different authorities have tended to recognize many different subfamilies, or sometimes split subfamilies off as separate families entirely (e.g., Disteniidae, Oxypeltidae, and Vesperidae); there is thus some instability and controversy regarding the constituency of the Cerambycidae. There are few truly defining features for the group as a whole, at least as adult…

Classification
- The Cerambycidae family can be classified into ten subfamilies, namely 1. Cerambycinae Latreille, 1802 This subfamily consists of more than 716 genera that include 3,889 species. Several genera and species of this subfamily are distributed widely in the America, of which, around 430 species belonging to 130 genera are seen in the Neotropical region of America. 1.

These beetles can be found in a wide variety of colors. A species referred to as Anoplophora Glabripennis is typically very large in size that ranges between 1 and 1.5 inches wit…
Life Cycle
- Some types of long horn beetle take 2 to 3 years to complete their life cycle. They do not enter into the pupa stage until they attain a certain weight. During the overwintering period, these beetles stay inactive, which is also known as “diapauses” condition. In the summer following the winter, they continue their lifestyle in an active way. This beetle larva initially develops a gallery f…
Feeding Behavior
- Most of the adult longhorn beetles feed on twigs, leaves and other matters of plant. In their original habitat, the larvae beetle eats parts of the healthy phloem, bark and xylem belonging to the Hardwood trees of any of the 24 species. That is why; these creatures are considered as harmful pests, because the trees on which they feed get damaged completely.
Reproduction
- Most of the beetles can fly up to a short distance of around 400 yards. But still, the chances of laying their eggs are more on the same host plant, from which they themselves have emerged. They tend to migrate to other places only when the population density of their original habitat increases. During the months of the summer period, the adult female who had already indulged i…
