松毛虫从巢中爬出 - 有毒害虫、危险与环境问题

l close-up capturing a pine processionary caterpillar (Thaumetopoea pityocampa) emerging from its distinctive white silk nest on pine tree branches. The image clearly shows both the characteristic silk webbing nest and an individual caterpillar visible as it exits, demonstrating the active behavior of these dangerous pests. The pine needles and branches frame the nest, illustrating the typical habitat and damage pattern. This compelling image documents an important environmental and public health hazard, as processionary caterpillars pose serious risks to humans, pets, and forest ecosystems due to their toxic urticating hairs. Perfect for pest control education, forest management content, public health warnings, environmental hazards, wildlife documentation, invasive species awareness, tree disease identification, pet safety alerts, and ecological conservation materials for editorial and educational use.
