Paragraph 2
Researchers set up LEDs at 26 roadside sites in the
that contained hedges or grassy areas. They counted the
of moth caterpillars found at these sites and compared these with insects found at
sites. A researcher said: "We were really

[the difference] was." He suggested that LEDs caused two
changes in behaviour. He said the lights stopped
insects laying eggs in the lit areas. In addition,
lighting disturbed the feeding
of the insects, so the caterpillars in the unlit areas were
