Who killed my blanket flower?

Planted 3 blanket flowers last July and despite the weeks of triple digit weather they did not die. This spring they grew back incredibly full and was so happy! I water my garden approximately 1-2 times a week. Over the weekend when I watered my blanket flowers, the fullest one looked a little sad but nothing I didn't think it could get over. Walked through my yard this evening and lo and behold someone killed my blanket flower! Is this a grub? An insect of sorts? Or is it not a creature but something else..? Thanks in advance. - Bess -
