Mines, Galls and Microfungi

By the front gate there is a small Hawthorn tree (Crataegus monogyna). Yesterday I spotted a small moth larva that turns out to be a young Light Emerald.

Apparently this species overwinters as small larvae lying flat along stems of the food plant. As you can see the larva has a fringe of hair-like projections hanging down from the sides.

Also on the Hawthorn a couple of leaves had been spun together with silk and inside was another moth larva. The identity of this one has not yet been resolved.

Before I left the premises I noticed a fungus on Solanum dulcamara (Bittersweet) which Bruce tells me is Alternaria solani.

This is not entirely good news as this fungus causes Early Potato Blight and we grow quite a lot of potatoes.

Moving on a couple of hundred metres to a strip of woodland by the Arish Burn, I noticed some leaf mines on Stachys sylvatica (Hedge Woundwort) caused by the true fly Amauromyza labiatarum.

and a little further on a Hazel (Corylus avellana) had leaf mines made by two different micro-moths.

Also there was a springtail, Entomobrya nivalis (sometimes called Cosmopolitan Springtail), though I almost missed it and have no worthwhile image to share.

A little further on there were galls on Ranunculus repens (Creeping Buttercup) caused by the fungus Urocystis ranunculi

I am grateful to various folks for identifying and confirming many of the species shown here: Bruce Ing, Roy Leverton, Murdo Macdonald, Stephen Moran, Nigel Richards and Mark Young.
