After the storm: A view of a patch of forest in El Yunque rainforest, before and after hurricane Maria.

This is a view from the Iguaca Aviary, of a patch of forest 
in El Yunque rainforest, before hurricane Maria.


The same place, after Maria.

A hideous little pest of Bletia patula and other local orchids


The damage to the florar parts of Bletia patula flower betrays
 the handywork of a curculionid bettle that attacks the flowers of orchids.


Checking the flower shows that the bettle is hidden behind 
the lip of the flower, sometimes you find two bettles together.


If the bettle feels the flower is being handled, it tries to hide deeper between
 the lip and the petals.  If it is further annoyed it comes out of hiding and tries to flee.


If the bettle comes out of hiding, its usual strategy is to run to
 the end of a floral part and from there fall to the ground.

This particular flower bettle damages the flowers of many kinds of orchids in my garden.  Its local abundance varies seasonaly.  At certain times of the year I can find from one to five chewing in my flowers.  I think this might have to do with the peak of flower production by local plants, but this is just a guess.  Rather than use insecticide on them, I exploit their fleeing response by putting a cup with alcohol or dishwashing liquid under the flower and shaking the flower gently.  The usual result is that the bettle takes a dive into the liquid and then goes to the great orchid flower in the sky.  Thankfully for most of the year they are not present on the garden,    
These bettles are surprisingly hard for such a small insect.  It is not easy to crush them.   But if you are moved to squash them, they do produce a satisfying crunchy noise when crushed.  I have seen damaging flowers of Bulbophyllum, Cattleya, Dendrobium, Oncidium, Peristeria, Sphatoglottis and Bletia among others.

Hurricane Hugo, a few photos from the aftermath of Hurricane Hugo in 1989.


This tree was defoliated and stripped of most of its smaller branches.  In this particular area most trees sustaine extensive damage but remained standing.

In this area the trees were stripped clean of leaves and lianas and only the hard woody stems remained.  Unfortunately it is not easy to get a perspective in this photo this makes trees with substantial sized look like twigs.  To get an idea of the size look at the lower left corner of the photo were the remains of a palm frond can be seen.

In this area the wind were so fierce even the bark was stripped of some trees.  The top of this was ripped away by the wind.

Seven days after the hurricane some roads were still impassable due to the massive tree fall.

This part of the forest had faced the full brunt of the wild and the main color was that of the bare trunks and surviving braches of the trees.  Leaves which usually covered everything are nowhere in sight.

Making the best of a bad situation some college students from El Verde Station go out to do some research.

These photos were taken seven days after Hurricane Hugo hit the northwest corner of the Island of Puerto Rico.  I was able to take them because Hector Colon invited me and Sandra Moya to see the damage inflicted by the hurricane to the forest of the area around El Yunque mountain, then know as the Caribbean National Forest.  We were shocked by the tremendous damage that the high wind inflicted to the forest.  In some parts it looked like someone had bombed the forest.  Bird mortality was high, as I recall half of all the Puerto Rican parrots in the forest perished as a result of the hurricane.  Other species were similarly affected. We traveled around the El Verde area.  We narrowly avoided being in the middle of a shoot out between cars that left several cars riddled with bullets by the side of the Espiritu Santo river bridge.  We were unnerved because we heard the shooting from the spot we were inside the forest a few hundred feet away from the bridge.  Although in some parts of the forest the damage was severe, in some sheltered parts the forest suffered much less damage.  But huge parts of the forest were defoliated in a way that I had never thought possible.  I took these photos and forgot about them for decades.  Due to poor storage they degraded considerably and some became damaged.  But even in their decay they give a powerful testimony of the awesome and frightful power of a tropical cyclone.
