Butterfly Season

After a cool spring that was not good for butterflies, we have quite a butterfly bonanza going on at the moment. Red Admirals and Whites (Small and Large) are the predominant species, but in the last week we also had Small Tortoiseshell, Peacock, Meadow Brown, Gatekeeper, Holly Blue, Speckled Wood and a Hummingbird Hawk-moth around the garden, with our lavender and neighbour’s buddleia being the centres of activity.

Prickly Lettuce (Lactuca serriola, #959)

A new plant growing on the gravel alley to the house - Prickly Lettuce (Lactuca serriola). This is the closest wild relative of cultivated lettuce, but it comes with prickles on the stem and the underside rib of the leaves. It is supposed to be edible, if with a bitter taste.

Red Solder Beetle & Dromius meridionalis

Here’s a couple of beetles that turned up recently. The ground beetle Dromius meridionalis was found in my moth trap the other morning. It’s a woodland species, often found under tree bark.

Red Soldier Beetle (Rhagonycha fulva) is common around the area, especially on the flowers of Hogweed and other umbelliferous plants. I don’t get many in the garden though - this one was on Welsh Poppies.

More July Moths

I posted some of the “macro” moths earlier - here are some of the smaller moths, including a few new species.

July Moths

Caught a really great selection of beautiful moths during the week, when we got our first dry and wind-free night for a while. There are a lots of different species flying at the moment, so here’s a selection of the 40 different species caught.(Second post with some micros to follow).

Marbled Green & Marbled Beauty

Marbled Green and Marbled Beauty are both moths whose larvae eat lichens. I catch the former quite frequently during their flight period in the summer, as they are common on house walls. Marbled Green is a new species for the garden, but it also can be found on limestone dry-stone and house walls with lichens. This one took me a while to identify as is it not the typical green colour usually seen.

Plain Golden Y (Autographa jota, #953)

It seems unfair to have christened this the “Plain” Golden Y, just because it has a prettier close relative in the Beautiful Golden Y. A first for my moth trap, with its pinkish colouration and golden spots I think it’s quite a fine-looking moth, even if this one is a bit worn. Flying in June-August, its caterpillars eat nettles.

Red Admiral (Vanessa atalanta)

Despite the wind and frequent rain showers we finally have a few more butterflies around, mostly Large & Small White, Meadow Brown, Small Tortoiseshell, Holly Blue and Red Admirals. Relatively few Red Admirals over-winter in UK, most Spring arrivals coming from the continent, with the first generation of UK hatched butterflies appearing about now. This species will be around until late autumn. The caterpillars are found on nettles mostly, and the adults love buddleia.

Common Black Ant (Lasius niger)

These black ants were emerging for their nuptial flight last week when the weather was hotter, drier and less windy. Winged males and females (queens) fly in order to mate, the queens going on to form new colonies and can live several years,while the males die off in a few days. These were all males, as the queens are larger. Usually they fly a bit later in the summer, but these were in the entrance to the greenhouse, so got an early start thanks to being in a warmer environment.

Cinnabar Moth Caterpillars

These stripey Cinnabar Moth caterpillars were on a Ragwort by the roadside just near my house. The moths are a bold red & black colour, but the caterpillars, which are often found like here in large groups, come in yellow & black stripes.

Ragwort contains toxic alkaloids which are unappetising (and in high doses even potentially dangerous) to grazing animals, however the moth caterpillars are able to sequester these toxins which affords them protection from insectivores. Black ants were also present, which are often associated with aphids, a few of which were also present. The ants can attack the caterpillars, presumably when they are small, to protect the plant for the aphids, which they then farm.

Ermine Moths

Ermine moths are common summer moths, so I thought it would be nice to look at three of them I caught at the weekend.

Often a pest on fruit trees their caterpillars are protected by a cocoon like a silken web around the leaves of the tree - in this case apple or bird-cherry. The Apple Ermine is pretty much identical in appearance to the Orchard Ermine (found on blackthorn, hawthorn or cherry) and the Spindle Ermine (Spindle tree). I put them down as Apple Ermines as I definitely have this species caterpillars on my apple tree. Bird-cherry Ermine does look a little different with neat lines of black spots. The third species is a Thistle Ermine, which is a bit bigger and actually though it looks similar, not from the same family - as the name suggests its caterpillars are found on thistles, but not in the same kind of silk web.

V-Pug & Dusky Pearl

I managed to unpack the moth trap before the rain started this morning and picked up a couple of new moths. The V-Pug is a fairly common species, with two generations in spring and then summer. It gets its name from the black “v”s on the wings. Dusky Pearl is a one-generation June/July micro with a preference for blackthorns

Hedgehog in the Shed

Tidying out the my rather run-down shed, I found a pile of leaves & twigs in the corner under a cupboard. After starting to rake them out an unhappy hedgehog emerged, so I put the nest back and hoped I hadn’t driven it away. And yes, photos on the trailcam show it is still there. We’ll put out some cat food for it periodically, so hopefully it sticks around.

Leopard Moth (Zeuzera pyrina, #949)

This Leopard Moth was hiding somewhere in a bunch of stuff I’d put outside to take to the tip. Leopard Moths are a one-generation summer moth, its caterpillars feed on leaves of a variety of different trees & bushes. I’m not sure if this one got a bit squashed when I was moving the rubbish around, or if was just playing dead.

Volucella inanis (#681)

This sturdy-looking hoverfly lays its eggs near the a wasps nest, where its larvae enter the nest ultimately eating a wasp larva before re-emerging as an adult. It looks a bit hornet like. This one was on a wall where we have a few mason bees and wasps, but it is a male (eyes join on the forehead) so probably was getting some sun rather than being on the look-out for somewhere to lay its eggs.

Varied Coronet & Short-cloaked Moth

Less moths this weekend, probably as there was a bit of a breeze, but there were a couple of smart new June/July flying species, as well as the Privet Hawk-moth posted previously.

The first of these, is a Varied Coronet (Hadena compta, #947). This is a relatively new species to the UK, unknown here until the 1940’s since when it has expanded its range across Southern England, but it is still not very common in Gloucestershire. Its caterpillars eat the seeds of Sweet William and Bladder Campion flowers.

The second new species is the Short-cloaked Moth (Nola cucullatella,948), which is a more frequently trapped species. Its larval food-plants include blackthorn, hawthorn and apple.

Chinese Character (Cilix glaucata) and Marbled Orchard Tortrix (Hedya nubiferana) are both species which hide in plain sight during the day looking a bit like a bird dropping, to hopefully avoid being eaten.

Small Insects attracted to Light

Especially in the summer moths, there are often a lot of small insects in the light trap along with the moths. Sadly these are mostly quite short-lived insects and are often dead or dying when you check the trap in the morning.

Water Veneer moths live only a couple of days. In June/July the winged males gather in large swarms to mate and are drawn to light. Females come in winged and flightless forms. These moths are aquatic, the males and flightless females mate at thew water’s surface, while the larvae live in slow-moving water where they feed on pond weed. the moths do fly quite far from water, so despite being quite far from any large pond or river I still caught 35 individuals at the weekend. The waterboatmen and long-horned caddisflies are also aquatic species that venture quite far from water and are attracted to light. The two caddisflies are both long-horned, which has a morph with patterned wings and a rarer one with plain ones.

The leaf-hoppers, close relatives of grasshoppers, are from closer afield in the nearby trees. There are a lot of similar looking leaf-hopper species and I was unable to find a good match in order to identify them. As well as these there were a few aphids and midges found their way into the trap.
