Field Notes
Description:
Black punctate weevil with a dispersed pattern of brown made from scales on the elytra. About 8 mm long. Family Curculionidae. This weevil is also parthenogenic, has fused wing elytra and is unable to fly. Grubs develop in the ground. A widespread garden pest in North America. This year is the first time I have seen it here in San Cristobal. At 2,200 meters, it is always cool and temperate in climate.
Habitat:
Semi-rural residential area, San Cristobal de Las Casas, Chiapas, Mexico, 2,200 meters.
Notes:
It drops to the ground suddenly when disturbed.
"At the beginning of the 19th century the distribution of Otiorhynchus sulcatus (Fabricius) (black vine weevil) was limited to central Europe. The weevil was a sporadically noted pest by vine growers with patchily distributed incursions. Today O. sulcatus is a common pest species with a distribution covering most parts of Europe and North America, parts of Central Asia, South America, new Zealand, Japan etc. (Moorhouse et al. 1992). The weevil causes serious economical damage on a large number of horticultural and agricultural crops." From: https://onlinelibrary.wiley.com/doi/pdf/10.1111/j.1601-5223.2010.02198.x
