Manual of the Odonata of New England

By R. HEBER HOWE, Jr.

Part I.

Mareh, 1917.

In 1905 Dr. P. P. Calvert published * a list of the Odonata of New England. Since that date a considerable number of * species have been added to his list, bringing the number known from this area to over one-hundred and fifty. Our distributional knowledge of species in the six states of this group has also been very much enlarged.

The present work is an attempt to supply a field manual of the New England Odonata for the use of all classes of students.

A pictorial key of genera, and illustrations of the diagnostic characters of species are given, in the hope that an easy recogni- tion of these insects will lead to a more general study of them. The habitat, abundance, limital dates of capture, and all known stations are recorded, and for the most part the ranges mapped.

The classification as given by Dr. Muttkowski in his Catalogue of the Odontata of North America (1910) has been adopted. The author wishes to espress his sincere thanks to Mr. E. B. Williamson, Dr. R. A. Muttkowski, Mr. L. B. Woodruff, Dr.

E. M. Walker, Mr. C. W. Johnson, Dr. Samuel Henshaw, Mr. Nathan Banks, Dr. R. P. Currie, Dr. F. E. Lutz, Dr. P. P. Calvert, Messrs. D. M. and B. K. Little, Mr. W. T. Davis, Mr. D. L. Dutton, Mr. A. P. Morse, and to my daughter, Miss S. A. Howe, for valued help.

Memoir of the Thoreau Museum of Natural History: II Manual of the Odonata of New England

By R. HEBER HOWE, Jr.

Part III.

August 30, 1918.

Note: Because the distribution of the Gomphines has been so little worked out for the New England States, as evidenced by the few records for each species, the distributional maps have been omitted in this part. The habitats, and limital dates are also very insufficient, but are included wherever possible. No drawings of the male appendages of G. adelphus have ever been published, nor am I able to secure a specimen from which to draw them.

Stigma diamond shaped.

Stigma almost rectangular.

Note: The form of the stigma is sometimes misleading, but an error made here is quickly apparent in following out the characters for the following genera. A cross vein in one of the forewings is sometimes absent, very rarely in both wings. The brown spot at the base of all wings in such unusual cases will serve to distinguish the species from the two foregoing species of Dorocordulia.

Note: The determination of the specimen from Concord recorded above was made by Mr. Williamson. From the series of specimens from Wareham, Mass., col- lected by Mr. O. Bangs and now in the Museum of Comparative Zoology in Cambridge, Mass., Mr. Banks and I were able to select two males and three females larger than the others, with four cells in the interior triangle (should be five) of the fore wings, and with three fourths of the stigma yellow. These specimens represent flavida of Rambur as distinguished by Dr. P. P. Calvert. The remaining smaller specimens, three males and two females, have only the typical three cells in the internal triangle, and one half the stigma yellow. It seems evident that flavida represents simply a variation in cyanea, a variation that occurs in individuals, and one that is duplicated in extent in many other species not recognized by name.

L. exusta is said never to have the thoracic dorsum pruinose but all the basal segments so, while in the variety julia the dorsam of the thorax is entirely pruinose, but only the first few basal segments of the abdomen. In exusta the black basal marking on the hind wing includes at least a part of the triangle; in julia it newer extends to it.

Memoir of the Thoreau Museum of Natural History: 11 Manual of the Odonata of New England

By R. HEBER HOWE, Jr.

Part VI March 15, 1920.

LARVAE OR NYMPHS

In this Manual have been treated only the adult or imago damsel and dragonflies. The nymphs which have had far less study are figured here only to show the Order characteristics. At some later date a complete treatment of them may be under- taken. The larvae or nymphs of the Odonata are aquatic. They inhabit ponds, lakes, brooks, and rivers, and their exuviae after the transformation of the imagos, are left attached to the stem of water plants, dead wood, or rocks, and are familiar to every student of nature. The works of Dr. J. A. Needham, Mr. Louis Cabot, and Dr. C. H. Kennedy include studies of many species, and will prove of much help in the study of the nymphs. The latter has kindly allowed me to reproduce drawings made by him.

Memoir of the Thoreau Museum of Natural History: II. Manual of the Odonata of New England1

By R. Heber Howe, Jr.

NYMPHS

ZYGOPTERA

Part I

December 24, 1921

The pictorial keys of the imagos of the Odonata of New England have met with such general and gratifying approval that the author begins with this paper a similar work on the larvae or immature stages of the species treated in the former work. Many of those persons thanked before are giving substantial aid in this portion of the manual, among them particularly to be mentioned are Drs. P. P. Calvert, P. Gar- man, E. M. Walker, J. G. Needham, C. H. Kennedy, C. B. Wilson.

In Part VI of the former manual, page 95, an introductory statement was made in regard to the habitats of the nymphs. In Dr. Garman’s valuable work on The Zygoptera, or Damsel- flies, of Illinois (Bull. 111. State Lab. Nat. Hist. 12: 411- 588. Pis. 58-73. 1917), complete descriptions and measure- ments are given for all but a few species here listed, and for permission to reproduce many of his figures of gill plates the author has both Dr. Garman and Dr. S. A. Forbes to thank. For permission to use the figure of the gill plates of Erwllagma ebrium { Ent. News 26: PI. 1. 1915) acknowledgement is due to Drs. Calvert and Cresson of the Entomological News. For the use of the figures of egg and first nymphal stage of Enal- lagma signatum the author is indebted to Dr. C. B. Wilson though the courtesy of the Bureau of Fisheries. For several figures of Lestes, etc., I am indebted to Dr. E. M. Walker. Two of the cuts used in the key are after published drawings by Dr. Kennedy. The full page plates were drawn for the author by Mr. E. N. Fischer.

Egg

1/

The eggs of the Zygoptera are ovoidal, about 1 mm. long, 200-300 of which are prob- ably laid by one female. They are inserted in a more or less definite arrangement in the leaves of grasses, sedges (bur reed), flag (Iridaceae) above or below (female submerg- ing) the water surface, and require a period of over 14 or 18 days to hatch, but the exact length of incubation is not known, though believed to be from 4-5 weeks.

Larvae, Nymphs or Naiads

After hatching the larvae are known as pronymphs. The nymphal life has been estimated at from 229-624 days. From 10-15 molts are re- quired for full devel- opment. Emergence generally takes place before 8 a.m., or after 6 p.m., though the nymphs of this order frequently emerge be- tween these hours. The cast skins found clinging to the stems of aquatic plants are called exuviae.

Food

The nymphs are both phytophagous and predacious, and have been recorded as feeding upon the following organisms:

Algae Diatoms Navicula Encyonema Gomphonema Synedra ulna Fragilaria Nitzschia acicularis Chlorophyceae Desmids Closterium Oedogonium Ulothrix Cyanophyceae Oscillatoria

Enemies

The eggs, and later during nymphal life the larvae are the prey of fishes of whose food they often comprise from 10-25 per cent. They are also preyed upon by Protozoa (Vorticella), Coelenterata (Hydra), Vermes (Nematodes), and by certain Hymenoptera, Coleoptera (Dytiscus, Zaitha), aquatic Hemip- tera, (Notonecta, Ranatra, Belostoma), Arachnida (including Mites), frogs, newts, reptiles (Chrysemys), and diving birds (Colymbus), as well as by larvae of their own or other Odonate species. They are attacked also by Algae (Oedo- gonium, Diatoms), and Fungus (Saprolegniales) growths.

Teneral Life

The freshly emerged imago, called a teneral, has been ob- served to take five and one half hours to complete its full development.

Libellula flavida

The Concord record must be expunged, as the specimen determined by Mr. Williamson has since been pronounced by Dr. Calvert as L. eyanea, though showing some misleading characters. The Wareham record is therefore also referable to L. eyanea. As the author had not listed definitely L. flavida as a New England spe- cies, because certain discrepancies were evident if the Concord species were true L. flavida — he wishes now to withdraw the last sentence in Ihe Note on page 70. L. flavida, Ramb., is apparently sufficiently distinct to be recognized.
