An orchid odyssey

Pink Butterfly Orchid (Orchis papilionacea) Martin Kelsey
Derek and Zena, Phyllis, John and Peter had asked me for a holiday focused on orchids in Extremadura and thinking about spectacle as well as diversity I recommended late March as the best time. In previous years they had challenged me on butterflies and dragonflies, as well as birds, so I was eagerly looking forward to this new odyssey. However, with the mild winter that we had experienced with some orchids already in flower in late January, I started to get rather anxious that the peculiarities of this year's weather might mean that the best was already over when Derek's group arrived.  I could not have been more wrong.  We have just completed an exhilarating and exciting exploration of our early spring orchids.

We started gently, combining birding on the plains west of Trujillo with a walk along a medieval drovers' trail. Here we encountered our first orchids of the holiday: Sawfly Orchids (Ophrys tenthredinifera), some Champagne Orchids (Orchis champagneuxii) and a single Pink Butterfly Orchid (Orchis papilionacea), a species that would subsequently figure highly in our memories.

But it was our second day when things really took off with our visit to the Cerro de Almaráz, the orchid hotspot in Cáceres province and a zone of higher pH soils amidst generally more acidic conditions. Here as well as the Sawfly and Champagne Orchids that we had already seen, we added the exquisite looking Mirror Orchid (Ophrys speculum), Conical Orchids (Orchis conica), Early Spider (Ophrys incubacea) and the gaudy Woodcock Orchid (Ophrys scolopax).

The Ophrys species are to me the most intriguing. The flowers have evolved extraordinary designs that mimic supremely attractive female bees or wasps, with pheremones produced as well, to entice desperate males to attempt to mate with the flower. No nectar is offered as a reward, but the lusty male insect passes from the lips of one flower to the next, bearing pollen on his body, thus ensuring cross-pollination. The closer one looked at the flower, the more weird and bizarre its structures and colours became.

Here we also found an early Tongue Orchid (Serapias lingua), which achieves its insect pollination by a different route, by offering a microclimate refuge inside the flower where the temperature is slightly higher at night than the ambient one.

But the most spectacular at Almaráz were the Naked Man Orchids (Orchis italica), tall and sturdy plants with hundreds of the pale pink flowering spikes on show.

Two days later we headed south to the pockets of limestone substrate near the town of Zafra. At one site, we added Sombre Orchid (Ophrys fusca) to our species list, but what remained with us as a lasting memory for the extraordinary sight of tens of thousands of Pink Butterfly Orchids in flower across a belt of rough grassland. It was a sight that became both breathtaking and overwhelming and which none of us had ever experienced before.

In another area nearby, we added the early flowering Giant Orchids (Himantoglossum robertianum) and Hill Orchid (Orchis colina), both species that I feared we might have missed this week.

The following day, in a area of damper ground, we found more Tongue Orchids in flower and also added Green-winged Orchid (Orchis morio).

On our penultimate day, we explored the area south of Mérida where in an area of old olive groves, we found a wonderful  selection of species, including Mirror, Naked Man, Conical, Pink Butterfly and Woodcock, and added the sublimely beautiful Yellow Bee Orchid (Ophrys lutea) and the highly localised Bumblebee Orchid (Ophrys bombyliflora).

But that day's spectacle still awaited us, in the Sierra de Utrera, where amongst thousands of flowering Iberian Fritilleries, were almost as many Green-winged and Champagne Orchids as well as the very stout and sturdy Heart-flowered Serapias (Serapias cordigera).

Early spring in Extremadura had reached its climax with 16 different species orchids, and the promise of more to come over the next few days, as rosettes of basal leaves of other species teased us, as their flowers would subsequently tease a generation of insect visitors.
