Dog-rose - Rosa canina

Blennocampa phyllocolpa

The larvae of the sawfly Blennocampa phyllocolpa gall the leaves of rose (Rosa) species causing both sides of the leaflet to roll downwards to the main vein, forming loose tubes, often spirally twisted. These may contain the green sawfly larvae, and may not be true galls.

Endelomyia aethiops

The larva of the sawfly Endelomyia aethiops feeds on roses, skeletonising the leaves. The larva has a transparent yellow-green body and orangey-brown head

Potato Aphid

The Potato Aphid (Macrosiphum euphorbiae) feeds on a wide variety of plants including Potato and Dog-rose. The adult wingless form is large 1.7 to 3.6mm and an elongated pear shape. It ranges from light green, yellowish green to pinkish red. It often has a darker stripe down the centre of its back, especially in immature nymphs. This species has noticeably long legs and two long tubes (siphunculi) at the rear end. The tail (cauda) is also long and finger shaped. The winged form has a much less distinct central stripe. The antennae and siphunculi are darker than in the wingless forms.

Rose Aphid

The Rose Aphid (Macrosiphum rosae) as the name suggests is to be found on various types of rose (Rosaceae sp) and mainly colonises tender flower buds, young shoots and lower surface of young leaves. The wingless aphids are medium-sized to rather large, broadly spindle-shaped, shiny, and pale to dark green or deep pink to red-brown or magenta, with shiny black head. Antennae and legs bicoloured, yellow and black.  The cauda is pale yellow. The adult aptera of Macrosiphum rosae is 1.7 to 3.6 mm long.

Rose Stem Aphid

The Rose Stem Aphid (Maculolachnus submacula) is  a brown aphid, covered in short hairs and with very short siphuncules.  Alates have a dark spot on the wing.  It usually feeds on the lower stems or roots of roses, including garden varieties, but can occasionally be found on other species in the rose and geranium families.  It is often attended by ants. 

Ectoedemia angulifasciella

The larva of the moth Ectoedemia angulifasciella mines the leaves of rose species and sometimes Salad Burnet beginning as a contorted gallery filled with brownish frass and then widening into a blotch with central or dispersed blackish frass.  

Rose Leaf Miner

The larva of the Rose Leaf Miner moth (Stigmella anomalella) mines the leaves of rose species. The mine is a long, sinuous gallery which often crosses back over itself. The frass is initially green and cloudy, filling the mine, but later is a thick black central line.  The transition between the two stages is very marked.

Coptotriche angusticollella

The larva of the moth Coptotriche angusticollella mines the leaves of various rose species and produce a pale, papery blotch mine on the upperside of the leaves. The mine often contorts the leaf causing it to fold upwards and may conceal the mine.

Agromyza sulfuriceps

The larva of the Agromyzid fly Agromyza sulfuriceps mines the leaves of various species in the Rosaceae family including Roses, Meadowsweet, Strawberry, Silverweed, Cinquefoil, Raspberry and Burnets. The mine starts as a long corridor, its initial part often along the leaf margin or a thick vein. Rather suddenly the corridor widens into a broad blotch. The corridor contains much frass, often in two distinct patches or lines.

Smooth Pea Gall Wasp

The Smooth Pea Gall is caused either by cynipid wasp Diplolepis nervosa or by Diplolepis eglanteriae on the leaves of the Dog-rose. The galls are identical and adults have to be bred and keyed out in order to record to species level, otherwise they should be recorded as Diplolepis eglanteriae/nervosa.

Diplolepis nervosa also produces spiked galls (sometimes known as sputnik galls) on Dog-rose, and these can be determined to species.

Sputnik Gall Wasp

The Sputnik Gall Wasp Diplolepis nervosa causes spiked 'sputnik' galls on the petioles, midrib or leaf blades of wild roses, usually underside but occasionally on the upper surface. 

Diplolepis nervosa also forms smooth pea-galls, but these cannot be distinguished from those of Diplolepis eglanteriae unless bred through and the adult keyed out. If smooth galls are not bred through they should be recorded as Diplolepis eglanteriae/nervosa.

Bedeguar Gall Wasp

The Bedeguar Gall Wasp (Diplolepis rosae) causes galls to form on Dog-rose. The galls usually develop on a bud, forming a large mass of long stiff branched hairs, green at first then red, and can be very numerous.  There are usually several chambers inside, and they are often  attacked by inquilines or parasitoids.  Occasionally small galls develop on leaves or hips.  

Diplolepis spinosissimae

The larvae of the gall wasp cause Diplolepis spinosissimae cause galls to form on various rose species, being most frequent on Burnet Rose (Rosa spinosissima), but also found on other rose species including Dog-rose and Sweet-briar. The galls are smooth, reddish-green, ovoid in shape and may occur on the leaf petiole or protruding from both sides of the leaf but quite often the galls coalesce.  Each gall contains a single white larva.

Dasineura rosae

The larvae of the midge Dasineura rosae causes galls on the leaves of various rose (Rosa) species such as Dog-rose. The leaflet is folded upwards along the main vein, thickened and pod like. This fold contains many larvae.

Rose Rust

Rose Rust (Phragmidium mucronatum) is a gall-causing rust that affects Rosa species in cluding Dog-rose; there is no host-plant alternation.  In spring bright orange aecia appear on the leafstalks, branches, leaf underside and any remaining hips. During summer yellow-orange uredinia then develop on the undersides of leaves, becoming interspersed with black telia in late summer/early autumn. It usually overwinters in the form of teliospores associated with fallen leaves.

Coleophora gryphipennella

The cased larva of the moth Coleophora gryphipennella feeds on Dog-rose. Cases and small circular transparent mines are commonly found on dog-rose.  The mines often have a small hole in the middle where the case was attached and through which the larva feeds.
