Chrysodeixis chalcites
In 3 days ~20% in a week ~40%
Chrysodeixis chalcites, the tomato looper or golden twin-spot moth, is a moth of the family Noctuidae, subfamily Plusiinae. It mainly lives in southern Europe, the Levant and tropical Africa, but can be seen migrating across much of Europe. In 2013, it was spotted in Canada. It is an important horticultural pest in New Zealand.
The length of the forewings is 15–18 mm. The moth flies from June to October.[1] The larvae feed on various herbaceous plants, such as Echium vulgare, Apium, Rubus, tomato, Fragaria and tobacco which is why it is perceived as a pest.
Chrysodeixis chalcites and Chrysodeixis eriosoma moths cannot be separated morphologically and they may be sibling species. They are distinguished by DNA, pheromones and geographic origin, as C. chalcites is found in the palearctic and C. eriosoma in the tropics and subtropics. The literature referring to C. chalcites in southern and eastern Asia or Oceania may actually refer to C. eriosoma. Wikipedia →

With luck
About 10% of wildlife watchers report a Tomato Looper sighting in Porto on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 194th most-seen of the 498 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.
February, April and July–December

GBIF citizen-science records
It is estimated from how often the Tomato Looper is recorded against all the insects logged in Porto (28 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.
