In 3 days ~10% in a week ~20%
Macaria abydata, commonly known as the dot-lined angle, is a moth of the family Geometridae. It is native from northern Argentina to the Caribbean and southern United States (southern states from Arizona to Florida, regularly wandering north to Colorado, Kentucky and other more northern states). It has been introduced to the Pacific and has spread rapidly since. The first introduction occurred in Hawaii in 1970 (recorded from all the main islands in 1984). Further spread occurred as follows:
The phrase "dot-lined" comes from the evidence of small dots along the postmedial and sometimes median line of both forewing and hindwing(anterior of the marginal band). Recorded host plants for larvae in its natural range are Vachellia farnesiana, Cassia, Sesbania, Parkinsonia aculeata and Glycine max. Larvae have been observed on Acacia koa and introduced Lysiloma latisiliquum and Litchi chinensis in Hawaii. In the Indo-Australian tropics it has been reared from Leucaena and Mimosa diplotricha.

Rare
Under 5% of wildlife watchers report a Dot-Lined Angle sighting in San Diego on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 314th most-seen of the 693 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dot-Lined Angle in San Diego on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Dot-Lined Angle sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
11th of 14
Of the 14 cities where we can rate Dot-Lined Angle sightings, San Diego ranks 11th at under 5%. The best odds are in Austin (United States, about 10%), Tuen Mun (China, about 10%) and Mesa (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Dot-Lined Angle is recorded against all the insects logged in San Diego (21 verified sightings), 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.
