Spittles, sometimes called cuckoo spits, are bubble formations that can be observed on plant stalks. Although it may seem like another nuance of the tiny members of the ecosystem, spittle is a sign that a spittlebug is residing on that plant and he is likely feeding on it.
The spittlebug can be likened to a ladybug. Its body also comes in red and black and is usually found on plant roots. They are often sighted on plants in the early part of the year. They transmit bacteria known as Xylella, which could inhibit the plant from growing healthy. Small garden plants to the large oak trees, can all be infected by the Xylella bacterium.
The curiosity of scientists about the existence and survival of the spittlebugs has only gone stronger. In fact, they are calling on volunteers to help them keep records of sightings of these little insects across the UK. The data collected will be used to help keep a map of the distribution of insects in an attempt to put an end to deadly plant disease in the country.
Xylella has poisoned a lot of plants in most EU countries. It caused the blighting of olive groves in Italy, causing a huge impact on the environmental balance and the economic aspects too. The United Kingdom is still clean from such an infection, but the authorities have put the country on high alert.
"There are more than 500 plant species that play host to the Xylella bacteria, so it practically affects a huge range of plant species from small ones to those that grow large," said Dr. Rebekah Robinson, lead researcher and senior plant pathologist from the Royal Horticultural Society.
"One of the worst things that this bacterial infection could lead to is that it could affect even the native trees endemic to the UK. Oaktree as well as various ash species like sycamore -- all of these can be infected by the bacteria. These are key plants in the country's landscape."
Scientists are calling on people to help in recording sightings of the spittlebug--may it be in their garden, a meadow, in the woodland, a grassland, or in the community area. The information gathered will be used to study the spread of such bugs and how they carry Xylella.
"Ultimately, the worst could happen. The disease could enter Britain. What this information gathering will provide is an opportunity to understand how scientists could stop it from spreading all too quickly," Robinson added.
