Change in the Weather

Ten years chasing dragonflies and I’m still in love with them. Being a seasonal treat helps to forward the interest; every April I can’t wait to spot that first Large Red.

Then a wait for the other Spring species to emerge, then, all of a sudden, there’s a bounty to sink your teeth into. The spectacle of mass emergence where every step reveals the glitter of tenerals.

Species counts rising rapidly; the first sojourn to the Somerset Levels and local favourites providing endless opportunities. If the weather stays sweet it’s a non-stop feast throughout May, June and July while August allows some time to kick back, relax and enjoy the spectacle of a pond or stream.

August can be a fantastic month if the water levels are high enough and the temperatures remain above 20 degrees. This year however most of the ponds were dry, regardless of the rains we’ve had.

August is the month for Hawkers and there’s few things I enjoy more than spending a few hours at a pond engaging with a resident Southern, Moorland, Migrant or a Brown.

When all you’re left with is puddles the only dragonflies you’re likely to encounter are the hardier, less fussy species, and there comes a time when you have to prioritise.

Now I can happily wait at a pond for something interesting to fly in, and with the Moorland here in the New Forest you normally have to wait for one to appear.

On the other hand you normally wouldn’t have to wait for a Southern; there’s usually one already on patrol when you arrive. None were waiting for me this year at Ramsdown, and I had to search hard to find one at Bramshill.

Surprisingly I’ve had females show first at both locations, and with just the one male (so far) at Bramshill found myself running out of options

Cadnam Common usually comes up trumps, but alas resembles a silage pit right now and all we saw was a lone Migrant patrolling the reeds of the island, so we made the short drive to Bentley Wood.

Always a gamble and after a fair walk in you keep your fingers crossed there will be something over the water. Thankfully on our visit on 1st September not only was there a male present but a friendly, gregarious individual who it was a delight to engage with.

At last! I had to wait until September for for the opportunity, but looking back I normally have my best moments with Southern in September.

Since then it’s taken a downward turn. A couple of friends were down this week for a little late Odo action and were disappointed; as was I when I ventured out on Thursday.

Too cool, too windy and mostly too dull, and I wasn’t prepared to root around for roosters as my stealth has taken a beating since an ankle injury a fortnight ago.

I had planned to venture forth today, but with only a possible 17 degrees I couldn’t bear the disappointment of another fruitless search.

If the temperature improves and we get a late blast of warm sunshine I’ll see things through until the end of the month. A late blast of enjoyment before Autumn takes hold and I can look forward to next season.

Meanwhile in Bramshill

With the miserable weather we’ve experienced recently it’s already feeling like autumn. You could be forgiven for mistaking this month for September.

Having to choose my destinations carefully to benefit from the most sun I chose Bramshill on Tuesday. As I haven’t been for a while I decided to take the long walk around the reserve, checking out the rides for roosting hawkers.

I didn’t have to wait too long for a sighting; the first being a male Southern Hawker which disappeared off at my approach, followed by a more agreeable female.

It as a delight to see the rides festooned with a large presence of Painted Lady butterflies. I counted at least 50 throughout the day, mainly feeding of Fleabane.

With a stiff breeze and too much cloud cover activity over the water was subdued, with only the hardier damselflies and Common Darters braving the conditions at the North-east pond.

Things were much better at Long Pond with a Migrant Hawker showing briefly, just enough time to grab and in-flighter.

Ruddy Darters were plentiful with many pairings and plenty of ovipositing – possibly the most I’ve seen in this section. Also patrolling was a Brown Hawker which, much to my surprise, landed on a Bulrush to finish his meal.

A female could be heard ovipositing in the depths and she took a little time out to perch.

During an extended spell of cloud I took a walk towards the small ponds, meeting a female Emperor perched in the gorse along the way.

The clearing containing the small ponds has really deteriorated now; impossible to fight a way through to even the nearest pond. I really hope they clear this soon. I had to be content with a visit to the Green Pond where only a few Ruddy, Common Blue and Common Emerald were present.

Despite my initial trepidation it turned out to be quite a rewarding visit.

Tales From The Riverbank

June & July are peak times for the streams of the New Forest. Whether you choose Latchmore, Ober Water, Silver Stream or Crockford you are always guaranteed a feast of favourites.

Keeled Skimmer, Golden-ringed, Beautiful Demoiselle, Southern and Small Red Damselfly all flourish, and depending on your choice you can add Scarce Blue-tailed and White-legged to the list.

When I’m not gallivanting off chasing rarities or running field trips I like to indulge myself in the peace & tranquility of a babbling brook, refreshing in even the humid heat of a glorious summer day.

Time spent strolling the water course, wading through fords or simply staying put to see who may visit, rarely are two days the same.

Within the eddies and flows are frequent, open pools created by livestock who come down from off the heath to bathe and drink. Here you can find Broad-bodied Chasers and Emperor holding territories.

Move on too quickly and you may miss the arrival of a female Emperor flying in to oviposit in the emergent vegetation.

In the faster flowing sections male Golden-ringed hold territories, chosen carefully to entice the females. If they have chosen a suitable place their seed is the one she’ll choose for the next generation.

If a coupling is successful they rise up in search of some peace and quiet for half an hour, usually a meter or two above ground, secluded in the shade of a gorse stand.

When this union is complete the male returns to his territory while the female deposits her eggs with frequent, violent thrusts into the gravel substrate of the stream.

Spend a few hours at one of the New Forest’s many streams on a warm, sunny day in the height of summer and you will not be disappointed.
