9 December 2016
Couple of months ago, I purchased few larvae of Megasoma punctulatum Cartwright with a friend. Then I received my portion of larvae, 4 of them, today on December 9th. M. punctulatum Cartwright is one of three Megasoma species, occurring in North America: M. punctulatum Cartwright, M. sleeperi Hardy, M. vogti Cartwright. M. punctulatum might be the most common one among those three, but not many numbers are being collected. So, I suppose I should say, ‘least common species.’ Hwang (2011) stated the species size can reach up to 40mm, but generally it seems it is in range of 20-30mm. They are known to active between July to August in Southern Arizona.
All are L2 larvae, and weigh only about 2-3 grams.
