Invertebrates of Mountain Lakes
Ninety-eight percent of all animal species on the planet are invertebrates: a perhaps uncountable and bewildering array of insects, corals, mollusks, hydras, jellyfish, sea stars, crustaceans, arachnids, worms, and other forms which don’t seem to fit in any evolutionary pigeonhole. By themselves, the beetles constitute over 350,000 species, a huge number and diversity that astounded Darwin and later biologists, who have puzzled over beetles species’ abundance for over a century, without an explanation.
There are many thousands of aquatic and terrestrial invertebrate species in Mountain Lakes, the presence of which can denote all kinds of environmental factors, positive and negative. Documenting even a small majority of them would be a study of years or even decades.
Listed below are two groups, butterflies and odonates (dragonflies and damselflies), which have received a great deal of study in recent decades. Most of them are indicative of the habitats present in the Borough, as well as the general condition of those habitats.
