Pitch is how high or low we hear a sound to be. If the frequency is higher, the pitch is higher. The unit of frequency is hertz. Ghz, or gigahertz, also can be used to measure frequencies. We can hear all the way up to 20,000 hertz! To conclude, the higher the frequency, the higher the pitch.
Several species of honeysuckle have become invasive when introduced outside their native range, particularly in New Zealand and the United States. Invasive species include L. japonica, L. maackii, L. morrowii, and L. tatarica.ost honeysuckle berries are attractive to wildlife, which has led to species such as L. japonica and L. maackii spreading invasively outside of their home ranges. Many species of Lonicera are eaten by the larvae of some Lepidoptera species â see a list of Lepidoptera that feed on honeysuckles.
There are nearly 180 different know honeysuckle species, most native to Europe and Asia, with only about twenty indigenous to the US. Honeysuckle is most often a vine, usually growing to a max of 20 feet.Some grow in a shrub-like form.Many species (especially those from Asia) are sold in the US for their beauty and for there attractiveness to hummingbirds.he honeysuckle seen here is Lonicera japonica or Japanese Honeysuckle, which is one of the two exotic invasive species of honeysuckle found growing wild in the United States (the other being the shrub Lonicera maackii).
