Lilac bushes are indeed known to attract certain types of wasps, particularly the European hornet. While many people may associate wasps with being nuisances or even dangers, it is important to understand the specific behaviors and characteristics of the European hornet in relation to lilac bushes.
The European hornet, scientifically known as Vespa crabro, is a species of wasp that is larger than the typical yellow jacket or paper wasp. It has a distinctive black and yellow body, and it is commonly found in Europe and parts of North America. Unlike other wasps, the European hornet has a unique lifestyle and feeding habits that can lead to damage to lilac bushes and other flowering plants.
One of the main reasons why lilac bushes attract European hornets is because these wasps are attracted to the sap produced by the plant. Lilacs, along with other flowering plants, release a sweet sap that serves as a food source for European hornets. These wasps will strip the bark off the branches and stems of lilac bushes to access the sap, causing damage to the plant in the process. This behavior is not typically seen in other wasp species.
Additionally, the European hornet uses chewed bark fibers to construct its nest. This papery nest is usually built in hollow trees, but it can also be found in other protected areas, such as attics or wall voids. The hornets will chew on the bark of lilac bushes and other trees to obtain the necessary materials for nest construction. While this behavior does not directly harm the lilac bush, it can contribute to the overall damage caused by the presence of European hornets.
It is important to note that while European hornets may cause damage to lilac bushes, they also play a role in pollination. Like other wasps, European hornets feed on nectar and pollen from flowers. While they are obtaining sap from lilac bushes, they may inadvertently transfer pollen from one flower to another, aiding in the plant’s reproductive process. This relationship between the hornets and lilac bushes is an example of the complex interactions that occur in nature.
To address the issue of European hornets damaging lilac bushes, there are a few strategies that can be employed. One approach is to physically remove the hornet nests from the vicinity of the lilac bushes. This can be done by contacting a professional pest control service or using DIY methods, such as placing a bag over the nest and sealing it off. It is important to exercise caution and wear protective clothing when dealing with hornets, as they can become aggressive when their nests are disturbed.
Another option is to discourage the hornets from targeting the lilac bushes by providing alternative food sources. This can be done by planting other flowering plants that produce sap or nectar, which may divert the hornets’ attention away from the lilacs. Additionally, maintaining good garden hygiene by promptly cleaning up fallen fruit or sap can help reduce the attractiveness of the lilac bushes to the hornets.
While lilac bushes can attract European hornets, it is important to understand the specific behaviors and characteristics of these wasps. The European hornet’s unique lifestyle and feeding habits can cause damage to lilac bushes by stripping the bark to access sap and using chewed bark fibers for nest construction. However, they also play a role in pollination. By employing strategies such as physically removing nests or providing alternative food sources, it is possible to mitigate the damage caused by European hornets and maintain the health of lilac bushes.
