Hawthorn Shieldbug, Acanthosoma haemorrhoidale

Acanthosoma haemorrhoidale

I found this splendid little chap in my garden. It’s an adult Hawthorn Shieldbug Acanthosoma haemorrhoidale a member of the Hemiptera an order of insects most often known as the true bugs. It will overwinter as an adult, often darkening before hibernation and will emerge again in the Spring.

The antennae in Hemiptera are typically five-segmented, although they can still be quite long, as can be seen in this photo.

Hemipterans have sucking/piercing mouthparts. The mandibles and maxillae are sheathed within a modified labium to form a ‘beak’ or ‘rostrum’ called a proboscis. This sharply pointed tube is capable of piercing plant tissues and is used to suck out the liquids – typically sap. When the proboscis is not being used it is folded flat against the underside of the body.

The young are called nymphs and resemble the adults to a degree although they are often mistaken as other insects.

Ashley Wood has produced a series of illustrations showing the life stages of a range of UK shield bugs, which is particularly useful for identifying the immature nymphs and the various instars.

Fire Bug – Pyrrhocoris apterus

Pyrrhocoris apterus

The recent run of warm weather here in the UK has been a reminder of how hot it was when I visited Cyprus in April. This little chap was one of the first insects I encountered in the village of Frenaros where my mum and dad now live. My reason for showing it here is that this strikingly coloured red and black bug, that looks as though it has an african mask painted on its back, may be spreading northwards into England. Recently it has been found in Devon. Previously there have been small colonies in Surrey and Sussex and sporadic reports elsewhere. Although Britain has traditionally marked the northernmost edge of its range it has been a native of Jersey and Guernsey in the Channel Islands for some time now. In the last decade the populations there have increased greatly. So it may be an insect worth looking out for in future.

It proved a particularly difficult subject to photograph. Being almost manically active due to the very warm temperature. It wouldn’t keep still, even for a fraction of a second, and so the vast majority of my photos were just slightly blurred. But I persevered over several days and eventually succeeded in getting this image. Read more
