Forest Insect Pests vs Forest Pests

The photos present in this App are intended to help foresters, urban landscaping employees, or others working with trees recognize some of the common pest insects affecting trees in North America and understand their life cycles and how they damage trees. The information was drawn from book, websites, factsheets, and some original literature. This App is not a guide for specialists. In many groups, such as the bark beetles and aphids, confirmation of species identity requires attention to details not visible in photos with comparisons to other similar species and use of keys. Sources for further information (websites and articles) are given at the bottom of each species' page.

Do you want to know the cause of damage to trees or shrubs in your area? For example, have you noticed damage to a tree caused by an unknown insect or a fungus in your forest, garden, in a city park, or just somewhere in the wild, and would you like to know what kind of species it is? We will be happy to help you resolve your pest identification issue. Just please fill out the following form and send us photos of the damage or the cause of the damage. We will try to identify it, and will inform you about the result by email as soon as possible. This system is exclusively focused on monitoring of pest species in Europe and adjacent territories.
