Adult Ips pini beetles commence their active phase within the early stages of tree life. This phase is characterized by the emergence of infestations in trees, which may be freshly damaged or have sustained damage during the winter months. Such infestations serve as a visible indicator of the beetles' activity and their impact on forest ecosystems.
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) [citation needed] species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families.
The first sign of an Ips infestation in a tree may be the discoloration of the needles that occurs when fungi block the xylem and prevent water transport to the foliage. [6] Several species of blue stain fungus can be vectored by the beetles, including those of the genera Ophiostoma and Ceratocystis. [12]

A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths (Lepidoptera), sawflies (Symphyta, a paraphyletic group which Apocrita (wasps, bees and ants) evolved from), and flies . Some beetles also exhibit this behavior.
This species was first discovered living outdoors in the United Kingdom in 1994. By 2002 it had become widespread in the London area, and spreading rapidly throughout. . Although it is susceptible to some pesticides, it is usually recommended that home growers pick off beetles by hand, or shake them off onto a sheet of paper to remove them, if the plant affected by them is intended for culinary p
Cockchafer feeds on deciduous plant and fruit tree leaves, including oaks, maple, sweet chestnut, beech, plum, and walnut trees. The feeding behaviour of larvae can cause severe damage to the plants. They feed on both the small roots of field plants such as grain, grass, tree, beet roots and the large part of crop rootlets.
Most of the beetle's life is spent as a larva, with only 30–45 days spent as an imago. Adults feed on leaf material above ground, using pheromones to attract other beetles and overwhelm plants, skeletonizing leaves from the top of the plant downward. The aggregation of beetles will alternate daily between mating, feeding, and ovipositing. An ...
