text = "Forewing length: 2.5–3.5 mm. Biostatus: Endemic. Distribution and frequency: Northern North Island, as far south as Hawke’s Bay and Taranaki. Often abundant, but inconspicuous. Habitat, seasonality and behaviour: Native forest, especially podocarp forest. Adults may be found from late November to March. They fly by day in sunshine, settling briefly on ferns and other vegetation, and have been observed swarming around flow- ering nikau palm. Life history: Very poorly known; larvae have been extracted from moss and from rotting wood. Notes: The family Micropterigidae is an extremely ancient lineage, and the adults retain functional mandibles, unlike all other adult moths. These mandibles are used to chew fern spores and pollen. There is a diverse fauna of 19 species in this family in New Zealand; they are found mostly in moist forest. The forewing pattern of shining white markings in Zealandopterix zonodoxa is variable."

我是编码新手，第一次使用 re，我知道这可能效率低下且简陋。我还制作了一个没有正则表达式的版本，只有一堆 if 语句，同样的问题。
