Along the Woodland Edge during May and June

 Walking along the woodland edge looking for insects is always enjoyable. In one of my favourite woods, there are substantial mint beds along some of the shady and damp rides which can be particularly productive.

Speckled Wood (Pararge aegeria) (male)

Vapourer Moth (Orgyia antiqua) (mid-instar larva basking)

Scabious Sawfly (Abia sericea) (male & female)

Tenthredo mesomela (Sawfly sp.)

Macrophya annulata (Sawfly sp.)

Carabus problematicus (Violet Ground Beetle sp.)

Wasp Beetle (Clytus arietis)

Denticollis linearis (Click Beetle sp.)

Green Tortoise Beetle (Cassida viridis)

(mating pair)

Gonioctena decemnotata ( Leaf Beetle sp.)

Hairy Shieldbug (Dolycoris baccarum)

Tortoise Shieldbug (Eurygaster testudinaria)

Nursery Web Spider (Pisaura mirabilis)

Along the Woodland Edge

 The woodland edge is made up of several different growth layers. Most woodland tracks are bordered by verges of grass and flowers which are backed by a scrub layer of plants such as bramble and bracken. Deciduous saplings such as birch, aspen and willow grow though the scrub and these are backed by mature trees such as oak, beech and pine. The aspect of these track-sides dictates whether they face the sun or are left in shade. Together, all these features provide many different niche habitats for wildlife, especially invertebrates.

Here are some images of what can be found during May and June.

Peacock (Aglais io)

Orange-tip (Anthocharis cardamines)

The male is courting this female who is showing her reluctance to mate by holding up

her abdomen.

Satellite (Eupsilis transversa) (larva on bramble)

This moth larva is a nocturnal feeder but constructs a shelter in which to rest during daylight hours.

Broad-bodied Chaser (Libellula depressa) (female)

Although dragonflies need water for breeding, they utilise the woodland edge to hunt for insect prey.

Four-spotted Chaser (Libellula quadrimaculata) (female)

This immature female is developing the wing markings of form praenubila.

Black-headed Cardinal Beetle (Pyrochroa coccinea)

Red-headed Cardinal Beetle (Pyrochroa serraticornis)

Green Tiger Beetle (Cicindela campestris)

This species is regularly seen on woodland tracks. 

The images show a mating pair and an ovipositing female.

Sabre Wasp (Rhyssa persuasoria) (female)

This species is the largest Ichneumon Wasp to be found in Britain. The female has an ovipositor that makes up half of her total length. 

 I came across this female busily preening herself. She measured about 8 cms.

Oak Sawfly (Periclista lineolata) (larva)

Its foodplant is oak but I found this one resting on a nettle leaf.

 

Tenthredo livida (Sawfly sp.)

Tenthredo mesomela (Sawfly sp.)

Rhogogaster viridis (Sawfly sp.)

Favourite Encounters during 2022

 As we approach the end of 2022 and look forward to the start of a new season, I have been looking back at some of my favourite insect encounters during the year. It has reminded me of some lovely moments.

Pearl-bordered Fritillary (Boloria euphrosyne) (female)

This species of butterfly is one that I really look forward to seeing in the Spring. My first sighting is usually of a male patrolling low over a woodland glade looking for a female but in 2022, my first sighting was of this female happily resting on a bluebell.

Downy Emerald (Cordulia aenea) (male)

This species of dragonfly is a stunning creature and rarely allows close approach but as I wandered through the bracken of a wealden wood, I saw this male at rest. The sun had gone behind a cloud for several minutes and I had enough time to plan my approach before the sun reappeared. Just before it took off, it looked up to reveal its sparkling green eyes.

White Admiral (Limenitis camilla)

This understated beauty had a very good year in my local wealden woods and I regularly saw up to half a dozen on the wing within the same view. I have enjoyed observing camilla for some years but had never before seen courtship that led to mating. I was thrilled to see such an event in 2022.

Silver-washed Fritillary (Argynnis paphia)

As with the previous species, paphia also had a good year and in recent years it has become more common and widespread in East Sussex woodlands. Consequently, the occurrence of the female form valezina has become more frequent. I had some good moments with this species.

(female) (form valezina)

I came across this female resting with her wings open in light rain. I managed to get my camera out just in time to get this one shot before heavier rain sent her to the canopy.

Sawflies.

I have taken a much closer interest in sawflies in recent years and I managed to have some good moments with these very fidgety insects.

Abia sericea (Scabious Sawfly) (male and female)

Tenthredo mesomela (female)

Tenthredo scrophulariae (Figwort Sawfly) (male)

Willow Emerald Damselfly (Chalcolestes viridis) (female)

Whilst focusing on this willow stem bearing ovipositing scars left by a previous female, this female landed, rather fortuitously, in just the right place.
