Stegobium paniceum
In 3 days ~20% in a week ~40%
The drugstore beetle (Stegobium paniceum), also known as the bread beetle, biscuit beetle, and misnamed as the biscuit weevil (despite not being a weevil), is a small brown beetle that infests a wide variety of dried plant products, where it is among the most common non-weevils. It is the only living member of the genus Stegobium. It belongs to the family Ptinidae, which also includes the deathwatch beetle, furniture beetle and cigarette beetle. A notable characteristic of this species is the symbiotic relationship the beetles have with a yeast-like fungus which is transmitted from female to larvae through the oviduct.
The drugstore beetle is distributed worldwide with higher prevalence in warmer climates. It is commonly confused with the cigarette beetle, as they have a similar size and coloring. Adults possess antennae ending in 3-segmented clubs, while cigarette beetles have serrated (saw-like) antennae. Their bodies are lined with grooves running longitudinally along the elytra, whereas the cigarette beetle is smooth.
Adult drugstore beetles are between 2.5 and 3.5 millimetres (3⁄32 and 1⁄8 in) long and have a reddish-brown colour with a cylindrical body. Larvae... Wikipedia →

With luck
About 10% of wildlife watchers report a Drugstore Beetle sighting in Tel Aviv on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 157th most-seen of the 264 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.
April, July–September and December
In those months about 10% of wildlife watchers report a Drugstore Beetle in Tel Aviv on a given day, against under 5% in January–March, May–June and October–November, the lowest months.
Yes
Of the 9 cities where we can rate Drugstore Beetle sightings, Tel Aviv has the highest daily chance: about 10%. Next come Belgrade (Serbia, about 10%) and Kyiv (Ukraine, under 5%).
GBIF citizen-science records
It is estimated from how often the Drugstore Beetle is recorded against all the insects logged in Tel Aviv (9 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.
