Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Platycis minutus - A net-winged beetle

Range & Status

Widely but very sparingly scattered across lowland southern and eastern England.

Regional Distribution

Discovered ' near Zennor' in 1976, when seven adults were found by D. Hemingway in a tree stump adjacent to the hedgeline in a narrow lane. It seems most likely that this was an accidental introduction with timber as such a large and conspicuous insect would not escape attention.

Habitat & Ecology

The larvae develop in large items of relatively soft decaying timber, especially Beech

Fagus sylvatica . Usually associated with ancient woodlands and pasture-woodlands.


Clearance of decaying timber, and lack of new generations of host trees.


General deadwood conservation measures.
