Table 3. Flight periods of NH Odonata by ten day period (e.g., May A = 1-10 May, May B = 11-20 May, and May C = 21-31 May). Numbers represent the totalnumber of records in the NHDS database for each period, not including larvae. <strong>The</strong>se totals do include exuviae, which under certain conditions can persist untilafter a species’ normal flight period is over. A red number in a column indicates that all records for that time period were of exuviae, and that the period inquestion was later than any recorded date for flying adults. Early dates in this table apply to either adults or early-season exuviae (e.g., records that pre-datedetection of flying adults), while late dates are restricted to adults. In cases where older data extend a species flight period beyond that detected during the NHDS,these early/late dates are shown in red, but actual numbers of records are not included in the table. Species not recorded during the NHDS, but for which flightperiod data are available, are indicated in red. No dates are available for Aeshna sitchensis or Ophiogomphus colubrinus, so these species are omitted from thetable.APRIL MAY JUNE JULY AUGUST SEPTEMBER OCTOBER NOVEMBER DECScientific Name 1 Early Late B C A B C A B C A B C A B C A B C A B C A B C ACALOPTERYGIDAE (BROAD-WINGED DAMSELS)Calopteryx aequabilis 05/20 09/12 24 26 40 12 12 9 5 1 1 1 1 132Calopteryx amata 05/29 08/09 6 12 12 17 6 7 8 5 73Calopteryx dimidiata 06/09 08/18 1 1 3 10 2 5 1 23Calopteryx maculata 05/20 09/13 2 39 48 52 39 59 61 54 44 32 14 2 2 449Hetaerina americana 07/30 09/23 3 7 1 4 6 1 23LESTIDAE (SPREADWINGS)Lestes congener 07/10 10/28 1 5 7 7 13 24 18 21 18 4 3 122Lestes disjunctus 05/28 10/18 1 1 3 4 6 26 39 27 34 46 15 10 10 222Lestes dryas 06/01 08/20 5 3 2 1 2 1 1 15Lestes eurinus 05/25 08/23 3 3 9 8 16 10 6 2 5 1 63Lestes forcipatus 06/11 09/26 1 1 3 7 7 7 8 4 2 40Lestes inaequalis 05/22 08/01 5 7 10 7 14 4 3 1 52Lestes rectangularis 06/02 10/23 2 6 4 13 19 30 34 46 36 19 20 10 240Lestes unguiculatus 06/16 09/20 1 1 2Lestes vigilax 05/28 10/6 1 5 10 13 41 47 57 48 27 26 4 2 281COENAGRIONIDAE (POND DAMSELS)Amphiagrion saucium 05/27 08/02 4 7 4 3 4 3 1 26Argia apicalis 06/16 08/17 1 2 2 2 3 10Argia fumipennis 05/18 10/02 1 2 14 13 19 53 74 68 53 65 34 13 11 423Argia moesta 05/20 10/02 1 2 6 20 14 24 37 29 17 23 8 7 5 193Chromagrion conditum 05/04 08/27 6 26 59 62 32 21 27 13 6 1 1 1 256Coenagrion interrogatum 06/13 06/27 1 1Coenagrion resolutum 05/20 07/04 1 1 3 3 8Enallagma annexum 05/20 08/26 1 2 2 2 7 3 1 3 3 1 25Enallagma antennatum 07/08 07/30 0Enallagma aspersum 05/16 09/30 1 2 4 10 5 13 28 36 21 21 19 9 6 7 182Enallagma boreale 05/11 08/16 5 13 8 8 6 3 7 5 3 58Enallagma carunculatum 07/06 08/23 1 1 235Σ 2
