The detection of a new species of insects is not unusual for Latvia, and it happens every year. One of the reasons for this could be climate change, which would result in the insect species moving north.
Piterāns noted that two days after he spotted the new species of caddisfly, it was also seen in the municipality of Carnikava.
Asked how quickly it can be assessed how the arrival of new species affects existing ones, Piterāns said that conclusions can be reached over time. However, his observations show that the naturally occurring species live well with those already in Latvia, filling in a more free niche. Invasive species that are introduced as a result of human activity tend to be more aggressive, said the entomologist.
