In 3 days ~20% in a week ~40%
Brithys crini, the amaryllis borer, crinum borer, lily borer or Kew arches, is a moth of the family Noctuidae. It is a garden pest in parts of its range, as their larvae damage the stems and leaves of lilies, especially lilies of the family Amaryllidaceae.
It is found in the coastal areas of Southern Europe and North Africa, south to South Africa. Furthermore, it is found in Japan and in Queensland and Northern Territory in Australia towards India and Sri Lanka. The wingspan of the moth is about 40 mm. Its head, thorax and forewings are very dark brown, but paler toward the wingtips. Sub-basal, median and postmedial indistinct waved lines are black. A curved submarginal ochreous line with ferrous colored lunules found on each side of it. There is a marginal black lunule series. The hindwings are practically white. Tarsi bear black and white stripes. In Europe the adults are on the wing in July.
There are several generations per year, though development slows down in cooler seasons, when the larvae sometimes overwinter by boring into the bulbs of the host plants. The moth lays clusters of a few dozen eggs on the host plant leaves. The... Wikipedia →

With luck
About 10% of wildlife watchers report a Lily Borer sighting in Table Mountain National Park on a given day, based on 86 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 57th most-seen of the 344 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March–September and November–December
In those months about 10% of wildlife watchers report a Lily Borer in Table Mountain National Park on a given day, against under 5% in January–February and October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lily Borer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Lily Borer sightings, Table Mountain National Park has the highest daily chance: about 10%. Next come Garden Route National Park (South Africa, under 5%).
Same family: Noctuidae
The closest relatives of the Lily Borer that you can see in Table Mountain National Park (family Noctuidae, Cutworm Moths and Allies) are Cherry Spot (about 10%), Suring Moth (about 10%) and Cotton Bollworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lily Borer is recorded against all the insects logged in Table Mountain National Park (86 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
