Black crickets (Gryllus bimaculatus) are a hardy, cold
tolerant cricket and can grow to over 30mm in length. Seven sizes
are sold, and are packed in tubs and bulk.
Black crickets are sold as hatchlings (3mm), firsts (5mm),
seconds (6-8mm), thirds (8-10mm), fourths (12-18mm), standards
(18-25mm) and large (25-30mm).
They are a good species of cricket for customers receiving
orders by courier or Royal Mail in winter, as they can tolerate
lower temperatures than the 2 brown species of cricket sold by
Monkfield. As with any insect, proper supplementation should be
given prior to feeding to your reptile.
