Common Whitebeam

Common Whitebeam - Sorbus aria agg.

Description

Whitebeams comprise a very complex group of species and hybrids, many of which are rare native species.  The species and several hybrids or cultivated varieties are commonly planted in parks, gardens and streets.   

The leaves in the Sorbus aria aggregate are toothed, and may be shallowly lobed.   The leaf undersides are densely tomentose - i.e. covered in short, white or greyish woolly and matted hairs.  The fruits are scarlet to crimson. 

Similar Species

Sorbus latifolia agg. and Sorbus intermedia agg. are commonly planted.  They differ in leaf-shape and colour of berries.

Identification difficulty
Recording advice

Photograph leaves, including undersides, and fruits

Habitat

Woods and scrub on calcareous soils as a native species, but widely planted in parks, gardens and roadside verges and often bird-sown and naturalised.

VC55 Status

Uncommon as a native species in Leicestershire and Rutland but very often planted and naturalised.

Further Information

Identifying Whitebeams is difficult due to hybridisation and the presence of planted and naturalised cultivated varieties and hybrids.  Examination of leaves and fruits of a specimen with reference to a key such as Stace 4th edition is usually needed to identify to species; they are therefore best recorded as species aggregates.

Parornix scoticella

The larva of the moth Parornix scoticella feeds on Rowan and Whitebeam and occasionally on Apple. A blotch is formed in the leaf which turns brown, and the larva pupates in a folded portion of the leaf.

Bucculatrix bechsteinella

Bucculatrix bechsteinella is a small moth with a wingspan of 7 to 9 mm. It is pale buff with brown markings. The leafmine produced by the larva is usually on Hawthorn, and is small and in a vein axil, with blackish frass.  The exit gallery is clear, and angular in shape.

Pear Leaf Blister Moth

The larva of the Pear Leaf Blister Moth (Leucoptera malifoliella) makes a distinctive round blotch leafmine in a leaf of Apple, Hawthorn or Pear with a spiral frass pattern in concentric rings, sometimes several mines in one leaf.

Phyllonorycter sorbi

The larva of the moth Phyllonorycter sorbi mines the leaves of Rowan or Bird Cherry, and occasionally on Whitebeam or other hosts in the Rosaceae, creating a long tentiform mine along the midrib/eaf-edge on Rowan. The under-surface has several sharp folds. The pupa inside is in a strong white cocoon. The mature larva is yellow with a pale brown head.

Eriophyes arianus

The midge Eriophyes arianus causes galls to form on the leaves of Sorbus aria.  The galls take the form of slightly rounded pustules raised on both surfaces of the leaf, up to 2 mm across, sometimes coalescing, and with the opening on either the upper or lower leaf surface. The galls are light green or yellowish at first becoming brown later.
