There are a lot of unique facts about spiders in this region.

The cane spider, as the name suggests thrives in the cane fields.

Yes, the Hawaiian happy-face spider (Theridion grallator) is considered a vulnerable and endangered species. Its population is threatened primarily by habitat loss due to deforestation and the introduction of non-native, invasive species into its delicate rainforest ecosystem. Conservation efforts are focused on preserving its native habitat.

The native happy-face spider is found exclusively in the rainforests on the Hawaiian islands of Oahu, Molokai, and Maui. Their survival is directly linked to the health of these specific native forest ecosystems, which provide the necessary environment and protection from non-native predators and ongoing habitat loss.
