Homoeolabus analis
In 3 days ~10% in a week ~20%
Homoeolabus analis, known generally as the leaf-rolling weevil or oak leaf rolling weevil, is a species of leaf-rolling weevil in the family of beetles known as Attelabidae. The leaf roll of an Attelabidae beetle is referred to as a nidus (plural, niduses or nidi)—the Latin word for 'nest'. The process of constructing the leaf roll is termed "nidification". The main purpose of a leaf roll is to keep the eggs safe during the gestation period. It is found in North America. It is often preyed upon by the obligate egg predator and nest thief; Thief Weevil.

GBIF citizen-science records
It is estimated from how often the Oak Leaf Rolling Weevil is recorded against all the insects logged in Austin (17 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.
