Long-winged Cone-head

Long-winged Cone-heads use a liquid bubble to regulate their body temperature on hot days

Thanks to Pinocchio I’m embarrassed to admit I had always naively assumed there were as a rule green grasshoppers and beige crickets. Of course in the insect world its never that simple as this striking creature that took up residence on one of my bulrushes reminded me.

The first day I spotted her I assumed she had had a lucky escape from the pond and wound up on the Bullrush accidentally after leaping away from a predator. But I became curious when I saw her the second day running so started rummaging around in field guids to find out what she was and what she was carrying.

It transpired that she was a female Long-winged Cone-head, or Conocephalus discolor ( also Conocephalus fuscus). Cone-head sounds a bit like an insult but it refers to the angled shape of the species’ head. There are several species of Cone-heads in the Bush-cricket family, all of which are omnivorous, have long antennae and the females carry long blade-like ovipositors. Long-winged Cone-heads are distributed in Southern England and East Anglia living in dry and damp grasslands.

I wondered at first whether the droplet was perhaps an egg bubble but apparently Cone-heads blow out globules of liquid which is used as a means to keep cool and control body temperature on hot days. The females only have one brood a year and chew a hole in hollow stems of reeds or rush, then insert their eggs using their long ovipositor.

According to Wikipedia, high population densities can also encourage the development of an extra-long winged morph which has aided the species’ ability to expand into new favourable habitat as the climate has warmed.

A bulrush seed spike, or inflorescence, can hold up to 200,000 tiny seeds dispersed by the wind over winter

This winter is proving milder than usual and, so far, snowless but winter can be beautiful in many different ways. Certainly enjoying the beautiful seedheads of various native wildflowers is one such pleasure for me. Typha latifolia or Common Reedmace, known simply as “Bulrush” to most of us, flowers mid to late summer, but the large cigar-like seedheads last right through winter. This Common Reedmace seedhead was gently dispersing its myriad tiny seeds into a light steady breeze on a golden winter’s day.

Wildlife Value of Bulrush / Common Reedmace

Bulrush offers much more wildlife value than first might appear. It is an emergent marginal plant so its protruding leaf and flower spikes offer an emergence route for dragonfly and damselfliy larva and anchor point as they leave their watery life behind to metamorphosis. Meanwhile its bushy base clumps offer dense shelter from predators to all types of creatures visiting the water’s edge including newts, frogs, toads, shrews and, if you’re lucky, water voles.

Common reedmace supports four moth species in all. The three larger or “macro” moths are: the Bulrush Wainscot, Nonagria typhae, Webb's Wainscot, Globia sparganii and the Rush Wainscot, Globia algae, all of which burrow into its thick stems. The aone small -”micro” moth - the Bulrush Cosmet, Limnaecia phragmitella lives in the Bulrush’s seed heads, along with other insects like the Bulrush bug Chilacis typhae. A further insect resident is the Common reed beetle Donacia aquatica, whose larval stage feeds on the Reedmace’s shoots and then pupates in its root system.

Gardening Value of Bulrush / Common Reedmace

Common Reedmace flowers, though unassuming, are a surprisingly delicate creamy white but undoubtedly its greatest aesthetic value is in offering year round shape and form to a pond margin thanks to its dense bushy nature and broad tall spikey leaves. Additionally, its tall, cigar-like cylindrical seedheads form in late summer offer striking structural interest right through the winter.

Bulrush has historically been much maligned by traditional gardeners for its vigour and indeed its prolific seedheads, which can contain up to 200,000 seeds each, do mean it can be quick to spread and selfseed. However it is very easily pulled out if it starts expanding too enthusiatically and is a great addition to almost any sized wildlife pond. In smaller ponds it may be a good idea to plant it in containers to help rein in its expansionist tendencies.

Plant Lore of Bulrush / Common Reedmace

Being a longstanding native of our lakes rivers and ponds and widespread right across the British Isles, Common Reedmace has nearly as many descriptive folklore names as its seedhead does seeds! Aruond 40 often colourful folklore names have been documented for it. Many such as Black cap, Blackie toppers, Blackheaded laddies, Black Puddings and Hard-head reference the early dark seed head phase, some like Candlewick, Chimneysweep, Pokers, Flue brushes allude to its tall spikes, yet others still including Cat’s tails, Pussies, Pussy tails, Flax-tail evoke its late winter stage shedding fluffy seeds. There are also the odd biblical, maritime and punitive variants including Devil’s poker, Holy poker and Cat'-o’-nine-tails. A few linguistically more obscure names are there too such as Dod, Gladden, Levvers and Seg (perhaps an earlier form of sedge).

Ironically its most common name, Bulrush, isn’t strictly correct. The true Bulrush is actually Scirpus lacustris (also Schoenoplectus lacustris), also an emergent native but in a different plant family and often also called Common Club-rush to avoid confusion.

Bulrush does carry one longstanding superstition, for some reason the seedhead spikes are traditionally believed to denote bad luck or death if brought into the house.

Culinarily its roots used to be used like potatoes and ground to make a high protein flour, while its new shoots were used as an asparagus substitute. Medicinally it was used as a diuretic and its leaves or roots were used to help sores and other wounds
