One of my wildlife aims this year has been to try to find as many new species, of all kinds, as possible, and I’ve been extremely lucky to have found many new-to-me bugs and beetles. These include Lesser thorn-tipped longhorn beetle, 4 January; My first Pine ladybird, 10 March; My first Eyed ladybird, 22 April; Fine streaked bugkins, 26 April; Cyllecoris histrionius, adult and nymph, 12 May; Cantharis decipiens, 13 May; Cacopsylla ambigua, 29 May; Rhopalus subrufus, 6 June; Rhabdomiris striatellus, 10 June; Bug: Deraeocoris flavilinea, 28 June; Beetle: Grammoptera ruficornis, 30 July; Beetle: Four-banded longhorn, 2 August; and Bug: Megacoelum infusum, 12 September.

I was particularly chuffed to find my first Juniper shieldbugs (Juniper shieldbug, 3 June) and, now that I know to look for them on some other tree species, I’ve managed to find them on four separate occasions, three of those in the same location as my initial find, on a Cypress growing in a local park, and the other on a different Cypress species growing in one of Cardiff’s oldest cemeteries, alongside Llandaff Cathedral.

Another new bug that I think is particularly attractive is Bug: Kleidocerys resedae. I wrote about that on 27 June, and this is another species that I’ve managed to re-find, on 15 November, when I spotted three different adult bugs within a few metres of each other.

As I think I’ve mentioned previously, I’ve been fortunate to find several new bugs and beetles this year. This is one of those, now seen twice one month apart. Let me introduce you to the Birch catkin bug (Kleidocerys resedae), a member of the Lygaediae, the seed bugs that live in, on and around the seeds of various plants. In this case, as you can tell from the name, Kleidocerys resedae can be found on Birch trees (Betula species), the nymphs in particular munching on the catkins.

These are attractive little bugs, generally red-brown in colour, with some paler markings and transparent wings. There is a darker form Kleidocerys resedae f. privignus, which can be found around Alder trees, and I wonder if the bug shown below might be one of those. I actually spotted it on scrub underneath some trees, one of which was an Alder.

Birch catkin bugs can be found throughout Britain, as well as in North America and Europe, and you might be lucky enough to see them at any time of year, as they overwinter as adults (though they are thought to hibernate in colder climates).
