In 3 days ~20% in a week ~40%
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.

With luck
About 10% of wildlife watchers report a Dot-Lined Angle sighting in Monterrey on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 121st most-seen of the 413 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.
October
In that month about 20% of wildlife watchers report a Dot-Lined Angle in Monterrey on a given day, against under 5% in December to June, the lowest months.
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.
Among the best
Of the 14 cities where we can rate Dot-Lined Angle sightings, Monterrey ranks 4th at about 10%, level with the leaders once rounded. 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 Monterrey (30 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.
