30 Days Wild – Day 9: Send in the Troops

Despite a bit of a stutter in the summer weather this week the season still advances and Day 9 of 30 Days Wild saw the first common tern chicks on the rafts on Ivy Lake. I think they probably hatched couple of days ago. One pair was a few days ahead of the main group so I am expecting a lot of chicks to hatch next week. Common tern almost invariably lay three eggs, so if they all hatch our 36 pairs will have about 100 chicks between them, so fingers crossed for a successful season.

I saw the terns from Ivy South hide where the grass snake were on show, basking on the stump below the hide.

The most significant sightings of the day though were once again of insects. I will always try to make a quick check of the hemlock water-dropwort at lunchtime, this plant is very attractive to nectaring insects and amongst these can be some rarer species. In particular it attracts bees, hoverflies and soldierflies. Blashford is a good site for bees, many of which use the dry lichen heath for nesting. Equally the wetland habitats are the home to many hoverflies and especially soldierflies, including some nationally rare species. So I was very pleased to spot at least one ornate brigadier soldierfly (Odontomyia ornata), a species that we see at Blashford every couple of years or so and has, so far, not been found anywhere else in Hampshire. I then spotted a second species, the black colonel (Odontomyia tigrina), slightly more often recorded but still quite rare, this one at least allowed me to take a picture.

However visiting flowers to feed, as these insects must do, is a risky business, there are predators lying in wait, in particular crab spiders.

Elsewhere on the reserve the three smaller lapwing chicks are still surviving in front of Tern hide along with the single larger one, I did not see the oystercatcher chicks and I suspect they may have lost one late on Thursday. We will see what next week brings.
