Creator Transcript
  • Ambystoma gracile (contd [continued]) [Northwestern salamander] May 20/42 [1942] In the same holes were observed mosquito larvae, hydrophybols[?] and possibly entomostracans [historical subclass of Crustacea, no longer in technical use] One bunch of Hyla [tree frog] eggs, about to hatch in one hole. In general, A. gracile appears to spawn only in pools fed by small trickle of water or in wide parts of trickle itself. No eggs or larvae were seen in larger streams or parts here of (Except last year when egg mass was seen in pool connected to Gravel Creek) nor in stagnant ponds in vicinity. The collecting ground is in a recently logg-off area; south of here where timber was removed at an earlier date there are fewer running streams + few ponds and no eggs or larvae were seen in any examined. Total lengths as follows (1) 64 (6) 61.5 (2) 85 (7) 64 (3) 85 (8) 67 (4) 56 (9) 63 (5) 63 (10) 56.5
