are at peak abundance this July, with 20 sightings recorded — more than any other species in a recent 100-plus moth flush across the scrub ridges. The timing is no coincidence: these nocturnal insects emerge in response to the humidity and moisture of the rainy season, their life cycles finely tuned to the atmospheric conditions that govern the region's hydrology.
These sandy uplands play a quiet but critical role in the landscape's water budget. Rainfall here infiltrates directly into the karst aquifer below, eventually feeding the springs downstream. That connectivity means the ecological health of the scrub — its vegetation structure, its insect communities, the very permeability of its soil — is bound to the water quality and flow reaching the impaired springs below. When moths like these thrive in the uplands, it suggests the groundwater system is still functioning, at least in this reach, even as downstream water systems struggle.
