Recent sightings – June to mid-July 2019

Our new bug viewers have been especially popular with our visitors, providing a glimpse into the normally hidden lives of a range of insects. One new resident is the leafcutter bee, which as its name suggests, cuts away sections of leaf from a plant, and then uses them to line its nest, typically in pre-existing cavities as we have here, or in rotting wood which they can burrow into themselves. The overlapping leaf sections form a cylindrical cell, in which is placed a single egg and a supply of pollen for the larvae to eat once it hatches. The cell is sealed with a single section of leaf. Once fully grown, the larvae will spin a cocoon and pupate, overwintering in the cell and emerging in the spring.

We also have mason bee larvae in the bug viewer, which as their name suggest, use various bits of masonry and stone to make a mud cap for their nests.

Both the leafcutter and mason bee are solitary bees – all females are fertile and there is no queen nor worker bees in the nest – there is no sharing of the work as the female does everything herself once she has mated with the male, constructing the nest and collecting pollen. Solitary bees also do not make honey or wax. Solitary bees are important pollinators, and many are polylectic, meaning they collect pollen from a wide variety of species. Leafcutter and mason bees have specialised hairs on the underside of the abdomen to collect pollen.

We are delighted that we’ve had two pairs of spotted flycatchers breeding on the reserve this spring, and we know that one pair fledged four youngsters. This is the first breeding record we have for spotted flycatchers for several years, and given the fact that their numbers plummeted by a startling 89% between 1967 and 2010, we are thrilled to see them successfully rearing young here at Lochwinnoch. These summer migrants are some of the latest to arrive to the UK, normally arriving around late April or early May and you should be able to see them around the reserve until September. Listen out for their characteristic “tseeep” call, and then see if you can spot them perching upright on a branch as they keep an eye out for flying insects to eat. They will often fly after an insect and then return to the same perch, a practice known as ‘flycatching’!
