Weevil: Curculio glandium

How cute is this little weevil?

This is Curculio glandium, also known as the Acorn weevil because it lives in Oak trees and the female of the species uses her long snout, her rostrum, to drill a hole in to the middle of an acorn, in which she then lays her egg using her ovipositor. It seems a difficult place in which to live but the weevil larva (sometime there’s more than one larva in each acorn) feeds happily inside the acorn through the cold months of the winter. I’m always a little dubious about information from Wikipedia but the entry there (scientific papers are referenced) says the ‘larvae are freeze avoidant, preventing their internal body fluids from freezing during the winter’. Presumably that means they have their own version of anti-freeze. The larvae emerge in the Spring to pupate, and the life cycle begins all over again.

F is for Figwort weevil

Weevils are some of my favourite insects, and the gorgeous Figwort weevil is, I think, the cutest of them all. Once I discovered where they lived in one of my local parks, I made sure to check their Figwort plants every time I went there and, as a result, I have lots of photos of them and have discovered more about their life cycle.

You might remember that, in June, I brought home a tiny cocoon. I had an idea what it might be but wasn’t entirely sure, and was fascinated to watch the ‘thing’ moving about within its casing as shown in the video on the blog (There’s an alien in my kitchen, 10 June). And then it hatched, my perfect tiny Figwort weevil, and I was over the moon, like a proud parent, and found great joy in returning it to its Figwort plant to live life amongst its family (The hatchling, and family, 12 June). Moments like these are why I spend so much time in Nature.

Weevil number 3

British insects, British weevils, weevil

For some unknown reason, the insects I’m seeing most often so far this year are weevils (there was An early weevil, on 16 February, and Weevil: Dorytomus taeniatus last week, on 28 February).

240304 weevil (1)

I’ve seen today’s weevil species at two different locations so far, and I’m thinking you’ll be able to guess what type of weevil it is from the plant it’s on. So, how about giving it a try? Name the weevil!

Weevil: Dorytomus taeniatus

This was the other new-to-me species I found during last Wednesday’s walk (see also Monday’s post about the Ghost slug), or rather, these were – three tiny weevils, which, I think, must be Dorytomus taeniatus.

The reason I think that is partly because they fit the description I found on the Nature Spot website: a ‘small weevil with a mottled dark and light brown appearance’, and partly because these weevils develop inside willow catkins, which is where I found them. One was even sheltering or, perhaps, not yet emerged from inside one of the catkins. My photos are not very clear, sorry – I’m going to look for more of these when/if the weather improves.

I can’t remember what led me to check the few bundles of dried Ash keys still hanging from a short tree alongside the path I walked this morning but I’m very glad I did because I found this stunning little weevil lurking amongst the keys. I’m sure this is the earliest date I’ve ever seen a weevil, more evidence if it were needed of how mild this winter has been.

Figwort weevils and larva

I love weevils! I’ve probably said that before; I’ll undoubtedly say it again. So, I was grinning like a Cheshire cat when I spotted these gorgeous mini-beasties.

230529 figwort weevil (1)

Perched on the tiny bundles of fruit of the plant they’re named for, these are Figwort weevils (Cionus scrophulariae). Their furry looking coats of beige and brown and light grey are pure decoration (imagine having a coat like that to wear!), and probably also good camouflage. And their impressive snouts are used for sucking the juices from their plant hosts (they can also be found on Mullein), though I don’t think these two weevils were feeding – I think they were egg-laying, as I noticed tiny blobs of yellow emerging from their rear ends, and I don’t think it was pooh.

Amazingly, I managed to find a Figwort weevil larva, something I’ve never seen before. I’ve lightened this photo to show the detail a little more clearly but, as the UK Beetles website explains, they are actually dark brown, ‘almost black, and covered in a shiny and sticky secretion which makes them distasteful to predators and is thought to give some protection from parasites’. I actually find it quite difficult to comprehend that this slimy slug lookalike morphs into the complicated character that is the adult Figwort weevil.

Leafmines: Orchestes signifer

British weevils, leafmines on Oak, Orchestes signifer, weevil, weevil leafmines

From my previous posts, including the recent A weirdness of weevils, I’m sure it’s obvious that I’m a huge fan of weevils, but I’d never given a thought to their life cycle until I found these leafmines. The mines are the work of the larvae of the weevil Orchestes signifer. The gallery mines follow the edges of Oak leaves before terminating in a small blotch. At that point, the larvae make themselves a case by cutting out the circular blotch, and, snugly encased, they drop to the ground to pupate. You can find a photo of the black-and-white adult weevil on the British Leafminers website.

British weevils, weevil

They’re tiny – some more so than others; they’re odd looking – those snouts; they come in a variety of colours – that red; and they’re very very cute. During recent walks, I’ve been seeing lots of weevils, of various sizes, shades and shapes, sunning themselves on leaves on trees and shrubs, so do cast an eye their weevil way.

First weevil

British weevils, Exapion ulicis, gorse flower, Gorse weevil, weevil

Woot! This teeny tiny beastie is my first weevil of 2022, as you can probably guess from the yellow flower it’s sitting on, a Gorse weevil (Exapion ulicis). I’ve read that they usually feed by poking their snout (properly known as a rostrum) into gorse stems and seeds but this one had its snout so firmly inserted into the flower that it looked like it would almost tip over.

Some snippets from the insect world around me:

200720 common red soldier beetles

A sure sign that it’s now high summer, Common red soldier beetles (Rhagonycha fulva) can be seen everywhere, especially on the flowers of umbellifers, demonstrating why they are often called bonking beetles.

200720 green-veined white (1)
200720 green-veined white (2)

Also caught copulating, these Green-veined white butterflies (Pieris napi) were being annoyed by a third of their kind, trying to get involved in the action.

200720 small copper

On the subject of butterflies, the second brood of Small coppers (Lycaena phlaeas) is now on the wing. This stunning specimen was only the second Small copper I’d seen this year, so was a very welcome sighting.

200720 nettle weevil

There’s nothing cuter than a weevil. This one is, I think, a Nettle weevil (Phyllobius pomaceus).

200720 ants on ragwort (1)
200720 ants on ragwort (2)

I found this odd: a colony of ants, farming a horde of aphids on this ragwort plant, have extended their nest up the very stem of the plant.

200720 meadow grasshopper

To finish this post, first, a Meadow grasshopper (Chorthippus parallelus) nymph and …

200720 long winged cone-head nymph

… another nymph, also often a meadow dweller, this time a cricket species, a Long winged cone-head (Conocephalus fuscus).
