Dock bug baby

I blogged about the Dock bug (Coreus marginatus) back in October last year and mentioned then that, in common with most bugs, these mini-beasties go through five larval / nymph stages before they become adults, though I had only ever seen the adult bugs … until yesterday.

I was indulging in the odd mouthful of ripe blackberry as I wandered around Cathays Cemetery when my hand was stopped in its reach by the glare of this little critter. It obviously had its eye on the succulent ripeness of that very same blackberry and was certainly not going to be intimidated by any gigantic human hand reaching towards it. I relinquished the berry!

Viburnum beetles

If you’re a gardener who cultivates any of the viburnum species of plant for their frothy flowers, vibrant berries and heady scent, then you probably won’t be very keen on these little beetles as they can make a pretty good job of chewing up all the leaves on your viburnum shrubs, as you can see from my photos.

Rather unimaginatively but most accurately, they’re called Viburnum beetles (Pyrrhalta viburni) and, as a flat-living non-gardener, I find them rather cute. Both the voracious larvae (when they hatch in spring and early summer) and the less hungry adults (when they emerge from pupation in late summer) like to feed on viburnum leaves though it seems plants usually survive ‘even the most severe defoliation’. Personally, I think it would be best to enjoy the lacy appearance of the chewed leaves rather than resort to killing the beetles – all creatures have their place in the overall scheme of things, and the beetles won’t affect the stunning flowers and berries.

What’s on the teasel, 1

This is the sight that greeted me as I wandered home through Dingle Park the other day.

A Sloe shieldbug (Dolycoris baccarum) had its head buried deeply into the gaps between the spines of a teasel flower head. The tiny purple flowers had finished so it wasn’t nectaring, and I would’ve thought the flower head too tough for it to be sucking plant sap, so what on earth was it doing?

This little Green shieldbug nymph (Palomena prasina), watching from a nearby grass stem (you can see it in the background of the first image), looked as confused and bemused as I was.

After a few minutes, the Parent bug backed out of its spiny possie but it didn’t move from the teasel.

This was a good opportunity to get a photo of the underside of the bug … but I never did discover what it had been doing.

Lacewings

All of a sudden I’m seeing Lacewings everywhere I look. Flying from May through to August, they’re usually creatures of the night, and they’re very partial to a fat juicy aphid (which is why gardeners love them and encourage them in to their gardens) but, just in the last couple of days, I’ve been seeing them during my day-time walks, often sitting on umbellifer flower heads, apparently drinking nectar.

There are 14 species of green Lacewings in Britain so I’m not sure which these are but, with their delicate green bodies, bright metallic eyes and gossamer-thin wings, they are simply exquisite.

Two more leafhoppers

I’ve been leaf-turning again and one thing you’re almost sure to find if you turn over enough leaves is a leafhopper. These are two recent finds, their identities now confirmed by the national recorder. Both are small – around 4mm long when adults, and both can be seen from around June to September.

Eurhadina cocinnia
These little guys have a preference for oak trees but can also be found on other deciduous tree, and are common throughout Britain.

170712 Eurhadina loewii

Eurhadina loewii
E. loewii prefers Sycamore trees and, occasionally, Field maple, and lives in most English counties and in south Wales, but hasn’t yet crossed the Brecon Beacons.

The two photos below are interesting, I think. The one on the left shows E. loweii in its larval form and the photo on the right shows an empty skin, after the larva has gone through one of several moults between its emergence from an egg until the time it’s ready to pupate.
