This summer a group of these sawfly larvae have defoliated the top of a small ornamental pine tree in my garden in Bliss Gate. They have been recorded here since 2014. There are still a few larvae present in the middle of September, but they will soon all have moved down into the soil where they spin overwintering cocoons in which to pupate. They will emerge as adults during next May or June.
Southern Wood Ants are commonly found in the Wyre Forest and in sunny places their large nests can be large and conspicuous. There may be up to 400,000 individual ants in one nest, almost all of which are worker ants. Winged males and new queens emerge between April and August and Kevin McGee has sent this excellent photograph of one of the queens he found in Wyre recently.
- Wendy Carter has sent these excellent photographs of Wood Ant (Formica rufa) workers carrying smaller live ants. Although this has been documented before, it is not clear why this behaviour occurs. The ant being carried is not struggling, so presumably it is not objecting to a lift back to the nest!
Wood Ants (Formica rufa) spend the winter months in a state of dormancy underground in their nests. Then, in the spring sunshine when the ground temperature is high enough, they can be seen massing together on top of the nest in large numbers as seen here. Their dark colour enables them to absorb the heat of the sun and when they return to the nest their radiated heat can warm the nest.
Despite its name, this is not an ant but an ant-like wasp in the family Mutillidae (Hymenoptera) in which there are 3 British species. These are parasites of halictine bees and crabronid wasps. The females have no wings, but are transported by the male whilst in cop. This female was found on bare sandy ground at Bliss Gate. This one looked like a queen ant, although had conspicuous waving antennae. They can sting if provoked and apparently stridulate when handled.
The Wood Ants (Formica rufa) that are commonly found in most of Wyre’s woodland have begun to emerge from their winter period of dormancy and when weather conditions are suitable they are out massing on top of their nests – quite a spectacle!
This unseasonably warm weather will have had a number of effects on wildlife. On December 17th 2014 at 13.30, when the temperature outside was 12°C, I spotted a bumble bee worker buzzing around the Mahonia flowers in my garden at Callow Hill. On closer inspection it had two full pollen baskets and as I watched it moved across to nectar on winter-flowering heather close by. Now is the nest that this worker is provisioning a continuation of the summer nest, or has a new Queen come out of hibernation early and started building a new nest already?
