#639 Heterotoma planicornis

This bug with its distinctive large/flat antenna segment lives in low vegetation such as nettles and eats plant matter, but also small insects like mites and aphids. Heterotoma planicornis hatches in May and lives for one season, over-wintering as an egg. It is quite common all across England and has also been introduced to North America and New Zealand.

Moth Trapping Wednesday

As well as the hawk-moths I posted earlier, there was a good selection of other moths including Brown Rustic and Hook-streak Grass Veneer, both of which were new ones for my garden. In total 52 moths of 25 different species. Some of the highlights below…

Fasciation in Feverfew

While looking at bugs I noticed that one of the Feverfew flowers (lower centre in the photo) is fasciated. This mutation, which in this case elongates the flower, can be genetic or caused by an insect-borne infection. While I have found a few other cases of similar mutations in Feverfew (Tanacetum parthenium) flowers on the internet, there’s no additional information on what causes this particular mutation.

Midsummer Hawk-moths

Three Elephant Hawk-moths in the moth trap and a fabulous Privet Hawk-moth on the fence nearby were the highlights from last night. Privet hawk-moth was a new species for the garden.

Azure Damselfly

I don’t get many dragonflies in the garden, so it’s always good to snap one - often a bit of a challenge using a phone. Azure Damselfly (Coenagrion puella) is not so heavily tied to water as most species, so turns up here from time to time. This one is catching some evening sun on my potato plants.

There’s also a Southern Hawker (Aeshna cyanea) zipping around the garden this evening; another of the more regular dragonflies I get. But there’s not much hope of capturing that on my phone.

Varied Carpet Beetle

This one is doing no harm, looking for pollen on a flower, but the Varied Carpet Beetle (Anthrenus verbasci, #871) is not something you want too much in your house. In the natural habitat the adults lay their eggs in birds nests and similar dry places with a supply of suitable food: animal and plant fibres, dead insects, dry druit, etc for the hatched larvae. In the house they can infest carpets, ventilation systems and cupboards storing food or clothes to the point they can do serious damage if not spotted first.

June Moths

The moth trap was quite well filled the other morning; moth numbers starting to build. The only new moth was a Clouded Brindle (Apamea epomidion), a single-generation moth that flies between May-July, and apparently does not come to light that frequently. Aside from this there was quite a nice selection of other moths, plus a shiny Whirligig Beetle (presumed Gyrinus substriatus). These beetles are usually found spinning around on the surface of ponds, but they do fly between water sources and can be attracted to light.

Dryad's Saddle

This large fungus was growing off a hidden tree root right in the middle of the path at my local nature reserve. It is a Dryad’s Saddle (Polyporus squamosus). The fruiting body of these fungi is always on the dead wood of a deciduous tree, either up a tree stump or growing out of a tree root just underground, like this one. They appears quite early in the season, in late spring to summer, but quickly decay and are eaten by fly larvae.

Apple Ermine Moths

When you catch the adults in the moth trap there are a few species of Ermine Moth that are virtually indistinguishable from each other, but you can reliably tell the species apart by the host for their caterpillars. One of my Apple trees has a few tents/cocoons of these Apple Ermine Moth caterpillars (Yponomeuta malinellus). There are not too many of them and apparently they are relatively harmless to the tree or the fruit, so I’m happy to leave the caterpillars undisturbed.

Woolly Aphid (Eriosoma lanigerum, #863)

Not wholly welcome, but one of the apple trees has a minor infestation of these Woolly Aphids (Eriosoma lanigerum). At first I thought it was mildew, but inside the while sticky wool there are lots of dark-coloured aphids. The colony was attended by some Harlequin Ladybirds, so hopefully natural predation can keep the aphid population under control.

Jubilee Moths

It looks like it might be a bit wet for the rest of the weekend, but last night was dry and there were a few moths in the trap this morning. Common White Wave (Cabera pusaria) was a new species, while this Clouded Silver (Lomographa temerata) was a well marked individual. Nothing red, white & blue though!

White Comfrey (Symphytum orientale, #862)

This rather pretty white flower that popped up under a bench out the front of the house is White Comfrey. Another new plant for the list. It’s actually not that common; unlike its purple relative Common Comfrey which is often grown by veg gardeners to make liquid fertilizer. White Comfrey is another non-native plant that has become naturalised across much of England.

Shepherd's Purse

This Shepherds Purse (Capsella bursa-pastoris, #859) popped up in the earth floor of the greenhouse. It’s a common enough weed, but this is the first time I found it in our garden - one of a handful of new plants I’ve found this Spring. It is considered a non-native plant in UK, introduced from Asia Minor / Eastern Europe in ancient times. As a member of the brassica family it is also edible, and even cultivated as a crop in parts of Asia.
