Puparia of the whitefly Siphoninus phillyreae are about 1 mm, oval, yellowish white, often medially with an elongated dark spot; dorsally a number of tubular filaments, each with a clear drop of honeydew at its tip and can be found on the undersides of the leaves of vaious trees and shrubs, but has been most frequently recorded locally on Hawthorn.

Pear Slug Sawfly

The larva of Pear Slug Sawfly (Caliroa cerasi) regularly feeds on Hawthorn, and sometimes other deciduous trees including Pear, Cherry. The larvae are black, slug-like and covered in mucus.

Social Pear Sawfly

The larvae of the Social Pear Sawfly (Neurotoma saltuum) feed in communal webs of up to 60 individuals on a variety of rosaceous plants including Hawthorn, Pear and Plum.

Rhamphus oxyacanthae

The larvae of the small, black weevil Rhamphus oxyacanthae usually mine Hawthorn leaves (but will ocasionally use other members of the Rosaceae family). The mines are usually small upper surface blotches, but later in the year on Hawthorn the mines may be larger - like a broad gallery or blotch - wth dispersed frass.  In this form they can look like a moth leafmine, but have a squat bright yellow larva, with a black head.

Orchard Ermine

The larvae of the Orchard Ermine moth (Yponomeuta padella) live in a larval web spun on Hawthorn, Blackthorn or Cherry.

Stigmella regiella

The larvae of Stigmella regiella mine the leaves of Hawthorn. The initial gallery is narrow and is filled with red-brown coiled frass.  It then turns abruptly to form a blotch with a thin line of blackish frass, which may be coiled or irregular. The larva is yellow with a pale brown head and has two diagnostic dark spots. The egg is found on the underside of leaf, close by or on a leaf margin.

Stigmella perpygmaeella

The larvae of Stigmella perpygmaeella feed on Hawthorn mining the leaf and forming a compact twisting gallery that usually becomes a 'false blotch' - where the gallery twists back on itself and touches the sides of the earlier part of the gallery.  The larva is yellow.

Eriophyes crataegi

These small, pale green patches on Hawthorn leaves are galls caused by the mite Eriophyes crataegi. Each blister contains numerous mites.

Apple Leaf Miner

The larva of the Apple Leaf Miner moth (Lyonetia clerkella) produces a leafmine on a number of species, especially Cherry, Apple, Rowan, Hawthorn, Blackthorn and other trees and shrubs in the Rosaceae family.  It is also commonly found on Birch. The mine is long, smoothly curved gallery with frass in a central line; older mines look whitish. The larva is long and slender. It has a segmented body and 6 dark feet.

Stigmella paradoxa

The larvae of Stigmella paradoxa mine the leaves of Hawthorn. A blotch mine is formed on the on leaf-lobe with central frass. The egg is found on the underside of leaf at the tip of a lobe (it is important to note this as part of your record).

Stigmella hybnerella

The larvae of the tiny moth Stigmella hybnerella mine the leaves of Hawthorn.  The leaf mine begins as a narrow gallery with frass in a central line, then becomes a blotch with scattered frass, although the linear pattern can usually still be seen.  The larva is pale yellow with a pale brown head.

Photo of the association

Phyllonorycter oxyacanthae

The larva produce a leafmine on the underside of a leaf, the mine is a blotch often causing the edges of a lobe to curl under.

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.

Ectoedemia atricollis

The larvae of the moth Ectoedemia atricollis mine the leaves of Hawthorn, Apple and other Rosaceae species. Initially, the larvae form galleries along the edge of the leaf, leading to a large blotch on the leaf margin. The larva has a distinctive black head, usually visible in the mine without being dissected out.

Stigmella crataegella

The larvae of the moth Stigmella crataegella mine the leaves of Hawthorn (Crataegus), creating a gallery which begins narrowly with linear frass. The mine then widens, and the frass is laid in distinct arcs, finally becoming irregular and central near the end. Larvae feed from June till August.

Parornix anglicella

The larval foodplant of the moth Parornix anglicella is Hawthorn, and the mine characteristics it produces are quite distinctive. In its later stages, the larva folds over a leaf lobe to form a diagnostic cone or flat fold.

Phyllonorycter corylifoliella

The orangey coloured adult is weakly marked in comparison to some of its congeners. The larva mines the leaves of Hawthorn (and also on Apple, Cherry and others), creating an upper-surface mine, usually over the midrib or vein; the mine is rounded in shape and flecked with blackish-brown frass when mature.

Taphrina crataegi

Taphrina crataegi is a fungus which causes pale green, yellowish or reddish galls on Hawthorn.  The galls are blisters, folds or bulges in the leaf, and often several leaves together are affected.  The galls are often flushed pink.

Gymnosporangium sp.

Hawthorn is the alternate host for two gall-causing rust species in the genus Gymnosporangium.  Aecia are produced on reddish swollen spots on leaves, fruits, petioles and shoot.  The aecia have long fringes (peridia) so the aecia have a pale brown whiskery appearance.  The aecial stages are very similar and species cannot be distinguished from field photos in this stage.

Hawthorn-Buttercup Aphid

The Hawthorn-Buttercup Aphid (Dysaphis ranunculicauses a gall on the leaves of Hawthorns. These yellowish galls cause the leaf to turn down like an upturned boat, and contain deep grey waxy aphids. The galls may be flushed rosy pink.  It alternates its host between Hawthorns and Ranunculus species but is most often recorded on Hawthorn.

Phyllocoptes goniothorax

Pale, curled edges on Hawthorn leaves are galls caused by the mite Phyllocoptes goniothorax. The rolls are only 2mm in diameter but can extend along most of the leaf margin, and affect lots of leaves.
