The
new species which I encounter during my travels are, of course, very
exciting. But I get a kick out of seeing species I am familiar with
from other locations in new settings. So here are two species which
are “old friends” that I have found in Peru recently:
|
Monarch, Argentina (the damn things won't sit still here) |
Everyone
knows the Monarch’s spectacular migration and wintering by the
millions in Mexico and thousands in California. Less well-known (to
us northern hemisphereans) a population exists across a broad swath
of South America (and Australia!). From Colombia down almost to
Patagonia in Argentina and Chile, little is known of this population,
but it is downright common in places.

Monarch egg, Pacora, Peru |
|
Asclepias cursavica, Pacora, Peru |
Here
the milkweed species is different from all are home… the
flowers are different colors and in less of a ball, and overall more
dainty and small. But it is similarly devoured by the larvae of both
Monarch and Queen butterflies (which occurs in the south of the US,
but not up by us). Monarchs are probably the most common large
butterfly here save Phoebis
sennae,
another old friend (though not common in the northeast).
|
I am 90% sure this is Phoebis sennae, the cloudless sulphur. |
The
other old friend around here is a fascinating one that I have
encountered in many places… but could encounter in many more!
Pantala
flavescens,
the so-called Wandering Glider, is a very common libellulid dragonfly
the world over. It is said that every island world-over with fresh
wáter has this species and I have read reports of swarms passing
over boats hundreds of miles offshore! Here they are absolutely
everywhere – often there are hundreds in view at a time. The
development of the species is very rapid, just a couple months… not
the year required by most dragonflies or the 5+ years required by
Phenes
raptor and
other petallurid dragonflies. I have seen them ovipositing here in
rice paddies, in small streams, large rivers and swimming pools…
|
Pantala flavescens, Bosque de Pomac, Peru |
And
to disabuse the notion that all I think of is insects… some birds,
too! Many species here are widely distributed, either in South
America (Rufous-browed Peppershrike, Tropical Gnatcatcher, Comb Duck)
or in the Americas in general. I am just as likely to see American
Kestrel, Peregrine Falcon, Turkey and Black Vulture, Lesser
Yellowlegs or Spotted Sandpiper (migrants), Killdeer (resident) and
House Wren here as in MA/RI.
|
Turkey Vulture, Bosque de Pomac |
|
Peregrine Falcon, juvenile?, a different subspecies than at home. Also it has been trying to catch my swallows... |
Other
species are quite different – such as this little tiny (<1”)
mantis - it wouldn't be interesting if too much were the same...
