It is a pest to green or red ash and white ash trees although any species of ash is vulnerable; female insects lay groups of eggs in slits in the leaflets of emerging leaves in late spring. [ 1 ] [ 2 ] [ 3 ] The larvae are greenish or yellow-white, and they grow to between 14 and 20 mm (0.6 and 0.8 in) long. [ 4 ]
These insects are commonly brought into homes with firewood and may emerge, but do no physical damage to the home. This species has been known to infest weak or newly planted living trees and is a pest of nursery stock in some areas. The feeding of the larvae may cut off sap flow, and in some cases weaken the trunk of young trees making them ...
Some states have more than one designated insect, or have multiple categories (e.g., state insect and state butterfly, etc.). Iowa and Michigan are the two states without a designated state insect. More than half of the insects chosen are not native to North America , because of the inclusion of two European species ( European honey bee and ...
In collecting buprestid prey, C. fumipennis has also been recorded collecting emerald ash borer (EAB; Agrilus planipennis), a pest insect known for killing North American species of ash trees. EAB has proven difficult to detect using traditional methods of ground/visual surveys and sticky traps, both of which are costly, labour-intensive and at ...
In most areas of Ohio, the tree canopies have started to change color. Some species of trees are on track for a typical fall-change timeline, while others are changing early after the dry summer .
In North America, the EAB is an invasive species, highly destructive to ash trees in its introduced range. The damage of this insect rivals that of chestnut blight and Dutch elm disease. [17] For perspective, the number of chestnuts killed by the chestnut blight was around 3.5 billion chestnut trees while there are 3.5 billion ash trees in Ohio ...
Invasive insects and pathogens are a serious threat to many forests in the United States and have decimated populations of several tree species, including American chestnut, American elm, eastern hemlock, whitebark pine, and the native ash species (see extended listing below). The loss of these tree species is typically rapid with both short ...
Image of black ash trunk. Tree is located in a seasonally wet, riparian habitat near a small-scale stream. Tree bark is corky and spongy. Black ash is a medium-sized deciduous tree reaching 15–20 metres (49–66 ft) (exceptionally 26 metres (85 ft)) tall with a trunk up to 60 cm (24 inches) diameter, or exceptionally to 160 cm (63 inches).
