Dendrolimus pini, the pine tree lappet moth or pine moth, is a pest species, a defoliator of coniferous forests. It belongs to the order Lepidoptera and is one of many lappet moths in the Lasiocampidae family. First described by Carl Linnaeus in his 10th edition of Systema Naturae (1758), it has a wide geographic range and has since been documented in Europe, Asia, and North Africa. D. pini has a preference for the Scots pine (Pinus sylvestris), its main host.
The scientific name Dendrolimus pini has both Greek and Latin roots. The prefix "dendro" is from Greek dendron, "tree". The suffix "limus" is Latin for "mud", which may be a reference to the moth's coloration. The epithet "pini" is the genitive of the Latin for "pine".
When first laid, the eggs are initially blue-green in colour, but over time they lose their colour, fading into a gray. The eggs are approximately 2 mm in size and take about 14 days to hatch. Larvae reach an approximate length of 2-3 inches. The caterpillar's thorax is covered in black hairs and made up of thick alternating steel-blue bands; the abdominal segments have a black mark bordered by irregular... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pine-Tree Lappet sighting in Berlin on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 646th most-seen of the 1065 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.
August
In that month about 10% of wildlife watchers report a Pine-Tree Lappet in Berlin on a given day, against under 5% in September to July, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Pine-Tree Lappet sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Berlin, in our data
Berlin is the only city on Wallace's Line with enough records to rate Pine-Tree Lappet sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pine-Tree Lappet is recorded against all the insects logged in Berlin (10 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.
