Here are some animals and plants you may spot when walking around the Triangle.

Female Black-Tailed Skimmer Dragonfly, Orthetrum cancellatum

First dragonfly we’ve noticed here this year (plenty of damselflies already): the handsomely marked yellow female of the Black-Tailed Skimmer, probably quite newly emerged. Males are pale blue with black tip to ‘tail’. 14 June 2012

Bumble-Bee male

Seems to be a male Bombus hortorum, but open to suggestions!

Flower Beetle (covered in pollen)

Lichened twig

Lichened twig. The round orange structures are apothecia, cups full of developing spores.

Grey Wagtail

Grey Wagtail on a branch in the pond, a Large Red Damselfly in mouth. It caught several damselflies in a few minutes.

The Grey Wagtail repeatedly darted into the air over the pond, snatching damselflies in flight and returning to the fallen birch trunk.

Azure and Large Red Damselflies

Coenagrion puella, Pyrrhosoma nymphula

Male Oedemera nobilis on an Oxeye Daisy

The beautifully iridescent male ‘Thick-Legged Flower Beetle’ has a sparkling green body and strangely inflated hind tibiae. Just in front of the Hut.

Female Oedemera nobilis on a Hawkweed flower

Oedemera nobilis, a brilliant green Flower Beetle, has a distinctive gap between the wing-cases. Here it is feeding on a Hawkweed on the Triangle’s acid grassland.

Bird-damaged Speckled Wood, Pararge aegeria

Bird-damaged Speckled Wood Pararge aegeria. The butterfly’s eye-spots have distracted insect-eating birds away from its head. Even with half a wing missing, this butterfly was still a fast and agile flier.

Yellow Iris, Iris pseudacorus

Yellow Iris, Iris pseudacorus, in the seasonal pond, 31 May.

Cinnabar moth, Tyria jacobaeae

Cinnabar moth, Tyria jacobaeae, 29 May 2012. The caterpillars eat Ragwort: they stripped the leaves from a plant in the Reserve.

A special visitor: Rose Chafer, Cetonia aurata

Water-Plantain in the Seasonal Pond

Coppiced Willow

An Explosion of Coppiced Willow!

The willows grow incredibly rapidly into a mass of long straight flexible rods, handy if you’re making baskets…. The picture gives an idea of the work needed to keep the reserve in good order. Coppicing creates a mosaic of different habitats from dense woodland to bright open areas to suit a wide range of animals and plants.

May: a Robin assisting Gunnersbury Triangle Volunteers

Robin eating invertebrates among cleared ivy

We celebrated May Day by clearing a strip of ivy from beside the main path. While ivy is wonderful, we have plenty of it in the Reserve, and the areas we’ve already cleared are bursting out into a rich mixture of grass and flowers. A Robin came to help, eating some of the many centipedes and insects dislodged by the work.

April showers .. with sunshine and flowers in between!

Female Sparrowhawk, an agile predator of small birds, seen here soon after a rarely-seen fight between two Sparrowhawks on the reserve (she has a claw-mark on her belly). Gunnersbury Triangle, 30 March 2012

We were lucky enough to have the Urban Birder with us when we saw the Sparrowhawks, so you can read about the event on his blog!

The Glorious Yellow Catkins of Pussy Willow, Gunnersbury Triangle, 30 March 2012

Bee-Fly, distinctive with its furry body, habit of hovering, and long straight proboscis, perched to clean its front legs. Gunnersbury Triangle, 30 March 2012
