Hellgrammite
Create your own realistic crocheted Hellgrammite (dobsonfly larva) with this detailed amigurumi crochet pattern by Tumannart.
The finished Hellgrammite is approximately 26 cm (10 in) long when made with the recommended materials.
This pattern is designed with a strong focus on realistic shaping and details, including the segmented body, colourwork, mandibles, antennae, legs, tail prolegs, and tracheal gills.
What’s included:
A detailed 12-page PDF pattern in English
US crochet terminology
Lots of step-by-step photos
Detailed instructions for the head, segmented body, legs, underside and small insect details
Two options for the lateral filaments:
sewn-on filaments for a more dimensional result
crocheted-on filaments for a faster method with much less sewing
Skill level
Intermediate / advanced
The pattern uses basic crochet stitches, increases, decreases, colour changes, working through front loops, and some construction techniques. The body is built segment by segment, with shaping and colourwork worked directly into the crochet.
Materials
Sport weight yarn
1.75 mm crochet hook
Safety eyes
Fiberfill
Tapestry needle
Stitch marker
Pins
The sample was made using sport weight yarn. Different yarn weights can be used, but the finished size will vary. With bernat blanket yarn you will make a huge Hellgrammite :)
Important
You may sell finished items made from this pattern with credit to Tumannart. Please do not copy, share, translate, or resell the pattern.
I hope you enjoy making this little creature as much as I enjoyed designing it!
